Description

Hi, I would like to autoscale SVG graphics produced by a call to ggplotly in order to fit them into the parent CSS container in a R Markdown document, as described here. For this, it is necessary for the SVG element to have a viewBox attribute that describes the bounding box of the visible contents. Do you think it would be possible to extend your package to include this attribute?

Cheers, Andrzej

Contributor guide

Research direction
Explore the internal plotly.R code that generates SVG output for ggplotly and locate where the SVG viewBox attribute can be added. Look for functions that handle SVG generation, such as `plotly build` or `toHTML`, and test adding `viewBox="0 0 width height"` to the root SVG element.
