Inversions Per Lap
Each point shows how many active inversions existed that lap relative to the starting grid order. Higher peaks indicate more overtaking activity.
Cumulative Inversion Curve
Running total of inversions across the race. Steep sections indicate high-action phases. Flat sections mean positions locked in for multiple laps.
Lap-by-Lap Position Tracker
Each line is one driver's position through the race. P1 is at the top. Lines end where a driver retired. Use filters to isolate specific battles or storylines.

Driver Position Changes
Positions gained (green) or lost (red) from grid start to final classification. DNF drivers shown in grey.
Position Heatmap
Rows = drivers, columns = laps. Cell colour = position: green (P1) → yellow (mid-field) → red (last). Faded cells = retired. More colour variance across a row = more movement for that driver throughout the race. Hover any cell for driver, lap, and exact position.

Race Chaos Timeline
Lap-by-lap breakdown of overtaking activity by type. Green = genuine on-track passes, orange = pit-cycle position changes, yellow = moves under Safety Car / VSC, red = DNF-induced gains. Yellow dashed lines mark neutralisation laps.
Overtake Classification
Breaking down how position changes occurred during the race. Only data from re-ingested races (fetch_race_data.py v2) will show full classification.

Adjusted Volatility
Three inversion curves for comparison. Raw: unfiltered (dashed grey). Pit-adjusted: removes drivers on in/out-laps so pit stops don't inflate inversions (green). SC-neutralized: SC and VSC laps weighted at 25% to reduce artificial compression effects (yellow).

Driver Battle Index
The most intense wheel-to-wheel fights of the race, ranked by a combined intensity score (position swaps + laps within 1 position). Higher = more sustained wheel-to-wheel racing.

What If No Safety Car?
Simulates the race volatility if all SC and VSC laps were removed entirely. Orange line = what the chaos curve would look like with pure racing laps only. Faint yellow verticals mark the removed neutralisation laps.

Momentum Tracker
Rolling 5-lap position change per driver. Positive = charging forward, negative = falling back. Shows who had the most momentum at each phase of the race. Defaults to top 10 finishers — use filters to explore all drivers.
