         * [Treemap](https://en.wikipedia.org/wiki/Treemapping)
         * is a common way to present "hierarchical data" or "tree data".It
         * primarily highlights the important nodes at all hierarchies in 『Tree』with
         * area.
         *
         * **Example:**
         *
         * [see doc](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap)
         *
         * **Visual Mapping:**
         *
         * treemap maps the numerical values to area.
         *
         * Moreover, it is able to map some dimensions of data to other visual
         * channel, like colors, lightness of colors and etc.
         *
         * About visual encoding, see details in
         * [series-treemap.levels](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.levels)
         * .
         *
         * **Drill Down:**
         *
         * The feature `drill down` means: when clicking a tree node, this node
         * will be set as root and its children will be shown. When
         * [leafDepth](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.leafDepth)
         * is set, this feature is enabled.
         *
         * **An example about drill down:**
         *
         * [see doc](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap)
         *
         * Notice: There are some difference in treemap configuration between
         * ECharts3 and ECharts2.
         * Some immature configuration ways are no longer supported:
         *
         * + The position method using `center/size` is no longer supported,
         * and `left/top/bottom/right/width/height` are used to position treemap,
         * as other components do.
         *
         * + The configuration item `breadcrumb` is moved outside `itemStyle/itemStyle.emphasis`,
         * and it is in the same level with `itemStyle` now.
         *
         * + The configuration item `root` is not avaliable temporarily.User
         * can zoom treemap to see some tiny or deep descendants, or using
         * [leafDepth](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.leafDepth)
         * to enable the feature of "drill down".
         *
         * + The configuration item `label` is moved outside the `itemStyle/itemStyle.emphasis`,
         * and it is in the same level with `itemStyle` now.
         *
         * + The configuration items `itemStyle.childBorderWidth`
         * and `itemStyle.childBorderColor`
         * are not supported anymore (because in this way only 2 levels can
         * be defined).
         * [series-treemap.levels](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.levels)
         * is used to define all levels now.

             * ```

             *
             * ```
             *
             * That is, we can configurate each node, can also configurate each
             * level of the tree, or set overall configurations on each series.
             * The highest priority is node configuration.
             *
             * `levels` is configurations on each levels, which is used most.
             *
             * For example:
             *
             * [see doc](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.treemap)
             *
             * **The Rules about Visual Mapping**
             *
             * When designing a treemap, we primarily focus on how to visually
             * distinguish "different levels", "different categories in the
             * same level", which requires appropriate settings of "rectangular
             * color", "border thickness", "border color" and even "color saturation
             * of rectangular" and so on on each level.
             *
             * See
             * [example](https://ecomfe.github.io/echarts-examples/public/editor.html?c=treemap-disk&edit=1&reset=1)
             *
             * The top level is divided into several parts by colors "red",
             * "green", "blue", and etc
             *
             *
             *
             * In each color block, `colorSaturation` is used to distinguish
             * nodes in sublevel.
             * The border color of the top level is "white", while the border
             * color of the sublevel is the color that based on the current
             * block color and processed by `borderColorSaturation`.
             *
             * `treemap` uses this rule of visual configuration: each level
             * computes its visual value based on the configurations (`color`,
             * `colorSaturation`, `borderColor`, `colorSaturation`) on this
             * level.
             * If there is no certain configuration in a node, it inherits the
             * configuration from its parent.
             *
             * In this way, this effect can be configured: set a `color` list
             * on the parent level, and set `colorSaturation` on the child level,
             * and then each node in the parent level would obtain a color from
             * the `color` list, and each node in the child level would obtain
             * a value from `colorSaturation` and compound it with the color
             * inherited from its parent node to get its final color.
             *
             * **Dimensions and "Extra Visual Mapping"**
             *
             * See the example below: every `value` field is set as an Array,
             * in which each item in the array represents a dimension respectively.
             *
             * [see doc](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.treemap)
             *
             * `treemap` will map the first dimension (the first item of the
             * array) to "area".
             * If we want to express more information, we could map another
             * dimension (specified by
             * [series-treemap.visualDimension](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.viusalDimension)
             * ) to another visual types, such as `colorSaturation` and so on.
             * See the
             * [example](https://ecomfe.github.io/echarts-examples/public/editor.html?c=treemap-obama&edit=1&reset=1)
             * and select the legend 'Growth'.
             *
             * **How to avoid confusion by setting border/gap of node**
             *
             * If all of the border/gaps are set with the same color, confusion
             * might occur when rectangulars in different levels display at
             * the same time.

                     *
                     * If all of the border/gaps are set with the same color,

                 * When `borderColorSaturation` is set, the `borderColor` is

                 *

                 * **How to avoid confusion by setting border/gap of node**
                 *
                 * If all of the border/gaps are set with the same color, confusion
                 * might occur when rectangulars in different levels display
                 * at the same time.

                 * In this time, series index can be refered as `{a0}`, `{a1}`,
                 * or `{a2}`.
                 *
                 * `{a}`, `{b}`, `{c}`, `{d}` have different meanings for different
                 * series types:
                 *
                 * + Line (area) charts, bar (column) charts, K charts: `{a}`
                 * for series name, `{b}` for category name, `{c}` for data

                 * name, `{b}` for data item name, `{c}` for data value, `{d}`
                 * for percentage.
                 *
                 * **Example:**

                 * ```
                 *
                 * **2\. Callback function**
                 *
                 * The format of callback function:
                 *
                 * [see doc](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.treemap.tooltip)
                 *
                 * The first parameter `params` is the data that the formatter
                 * needs. Its format is shown as follows:
                 *
                 * [see doc](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.treemap.tooltip)

                 * When
                 * [trigger](https://ecomfe.github.io/echarts-doc/public/en/option.html#tooltip.trigger)
                 * is `'axis'`, or when tooltip is triggered by
                 * [axisPointer](https://ecomfe.github.io/echarts-doc/public/en/option.html#xAxis.axisPointer)
                 * , `params` is the data array of multiple series.
                 * The content of each item of the array is the same as above.
                 * Besides,
                 *
                 * [see doc](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-treemap.treemap.tooltip)

                 * 2.x is not supported anymore.
                 *
                 * The second parameter `ticket` is the asynchronous callback
                 * flag which should be used along with the third parameter
                 * `callback` when it is used.
                 *
                 * The third parameter `callback` is asynchronous callback.
                 * When the content of tooltip is acquired asynchronously, `ticket`
                 * and `htm` as introduced above can be used to update tooltip
                 * with callback.

                     * Tips:
                     *
                     * When `borderColorSaturation` is set, the `borderColor`
                     * is disabled, and, instead, the final border color is
                     * calculated based on the color of this node (this color
                     * could be sepcified explicitly or inherited from its parent
                     * node) and mixing with `borderColorSaturation`.
                     *
                     * In this way, a effect can be implemented: different sections
                     * have different hue of gap color repectively, which makes
                     * users easy to distinguish both sections and levels.
                     *
                     * **How to avoid confusion by setting border/gap of node**
                     *
                     * If all of the border/gaps are set with the same color,
                     * confusion might occur when rectangulars in different
                     * levels display at the same time.

                     *
                     * Noticed that the child rectangles in the red area are
                     * in the deeper level than rectangles that are saparated
                     * by white gap.
                     * So in the red area, basically we set gap color with red,
                     * and use `borderColorSaturation` to lift the saturation.
