We might also want to add a dataviz-specific color palette to provide additional colors beside our base UI colors. This article for example shares great examples of color blindness-friendly palettes. There's also this website about color palettes for cartography.

On the topic of dataviz guidelines we might also get some inspiration from this collection of existing data visualization guidelines put together by the Data Visualization Society.

+1 to this suggestion. Currently we pretty much only use the blue Accent colour, which is the same colour for buttons, links, etc which can be quite limiting for datavis (eg, pie , stacked bar charts, comparison charts), and potentially may get distracting if half a page is in this colour.

Yes I agree. Data visualisation, similar to illustration, has wider needs so should have more flexibility than the simplified UI palette provides.

Thanks for sharing those resources @AAlhazwani-WMF.

@KieranMcCann I've found another real use case for charts:

You can check it when you Compare selected revisions in the "View history" page. Then you need to select the "Browse history" and this interactive chart opens.
