Vizlib color palette
In general, is there a way to update the vizlib color palette? I am using a dark background and the dark colors within the vizlib supplied palette's don't pass accessibility. Also, I wanted to update them to go with other extension palettes so that whatever charts the user decides to use (vizlib or other), they will have the same colors giving it a more cohesive look.
This is not a feature we currently support although you should be able to use Custom Charts.
Additionally, We are looking to expand implementation of Templates for more charts which could help with the cohesive look for the charts in your app.
