Example Calls

Show me where on track I'm fastest and slowest

analyze(analyzers='track_heatmap', event='01H8SP4HK4', lap_selection='best', value_column='speed')

Creates speed heatmap of best lap with color from slow (blue/purple) to fast (yellow/red)

Visualize my throttle application on the track

analyze(analyzers='track_heatmap', event='01H8SP4HK4', value_column='throttle', colormap='viridis')

Shows throttle position (0-100%) overlaid on track layout
