== Background
Result of spike T369863. Charts currently can be any size. This creates problems on mobile where charts will scale to the size of the screen. We think it would be sensible going forward to support 2 chart sizes: full screen and floated (for elements on the side)
== User story
As a reader I want to be able to consume charts regardless of screen size without having to open the SVG in a separate tab or switching to desktop mode.
== Requirements
[] Width is replaced with a new boolean option: fullscreen
[] When fullwidth the chart should take up 100% of the available ~~screen sizE~~ container size - for example if the chart is inside an infobox it will take up the full size of the infobox.
[] When fullwidth=false the chart should take up 50% of the available screen size on desktop breakpoint. Below desktop breakpoint it should go full screen.
=== BDD
