When there is a serial bar chart with many categories for a variable, it would be helpful for a user to be able to select a bar and it to change its color fill or outline to distinguish it from the other bars. Our specific example uses a bar chart with a variable that represents ~90 counties. The bars are currently set to all be the same dark green color, but we could see instances where someone from a particular county wants to see what their value is clearly compared to the other counties. If this advancement was implemented, someone from a county could select their bar, and it would show as a different set color, clearly putting it into context with all other counties.
