Better data viz for comparing trip times

Check out the trip summaries tab. The purpose here is to determine if map changes are helping or hurting trip times of people in aggregate. There's two views of that data right now, with some options for filtering. I've got a few ideas for better heatmap-inspired viz, or maybe you have an idea how to represent this kind of duration comparison more clearly.

Find the trip summaries tab in the UI. Examine the existing data views and filtering options. Research heatmap or other visualization techniques for comparing aggregate trip durations. The goal is to propose and implement a clearer visual representation to assess the impact of map changes on travel times.
