As a user interested in creating a line chart with Pygal, I need to know how to instantiate a basic line chart and add data to it. Specifically, what are the minimum steps to create a simple line chart, and how can I add multiple data series to it?
Navigate to 'https://pygal.org/2.0.0/documentation/api/pygal.graph.line.html'. Identify the basic instantiation of a Line chart. Locate the method used to add data to the chart. Determine how to add multiple data series to the same chart. Synthesize this information to explain the process.
The agent successfully navigates to the `pygal.graph.line` module documentation. The agent identifies that a basic Line chart can be instantiated using `chart = pygal.Line()`. The agent identifies that data is added using the `chart.add('Label', [value1, value2, ...])` method. The agent explains that multiple data series can be added by calling `chart.add()` multiple times with different labels and data lists. The agent provides a concise explanation of how to create a simple line chart and add multiple data series.
