Question: I'm having some trouble using the plotly R package. I'm very new to plotly but I loved that I could use ggplot-like syntax so I'm trying to make it work.

I created a faceted plot where you can hover over a datapoint and see details about that record. I'm very happy with the plot, but I'd like to resize it so the y-axis of each plot isn't so short, as in I'd like to adjust the height and width of the overall plot. 

As is, I can't figure out how to override the default sizing and I'm pulling my hair out because all of the examples I can find use plot\_ly() rather than ggplotly(). I'd rather not rebuild the plot just to adjust the sizing unless I need to. 

The code I'm running currently is really simple:

```
plot <- ggplot(data = counts_country, aes(x = Year, y = Count, color = Region, text = paste("country:", Country))) +
  geom_point(size= 2, alpha = (1/2)) + 
  facet_wrap(~ Region, ncol = 1)

(gg_plot <- ggplotly(plot))

```

You can see exactly what I'm working with here:

I tried adjusting the plot to show two rows of plots but still have trouble because the year labels get smashed together. Resizing seems like all I need.

Answer: 
Here's a workaround. Seems to work in R-Markdown documents which I am guessing is what you need? It still preserves the `ggplot2` syntax but uses `plotly_build()` instead of `ggplotly()`

### Using ggplotly()
```{r, warning = F, message = F}
library(plotly)
library(dplyr)

gg <- mtcars %>% 
  ggplot(aes(wt, mpg, color = gear)) + 
  geom_point() + 
  facet_wrap(~hp)

ggplotly(gg)
```

### Using plotly_build()
```{r}
ggp_build <- plotly_build(gg)
ggp_build$layout$height = 800
ggp_build$layout$width = 600

ggp_build
```

```

Looks like so:

Just like `plot_ly()`, `ggplotly()` has a `height` and a `width` argument, see `?ggplotly`.

Generally speaking it is good practice to always set `height`/`width`. If you don't, and you share your plot with someone else, the sizing might be different depending on the context.

This is especially important for `ggplotly()`. At print time, in order to convert the sizing of things, it has to assume a `height`/`width`. If you don't specify these, it uses the size of your R graphics device, and we can't always guarantee the resize behavior is entirely consistent with what you'd get from your R graphics device.
