NOTE: Full version of this Notebook is at Kaggle.

This notebook shows race traces for each F1 race in 2011, using the Formula 1 Race Data data set, which is sourced from ergast.com, and the Formula 1 Race Events dataset using data from Wikipedia.

Race traces provide an excellent way to visualize the progress of an entire Grand Prix. They show the gaps between cars, the general field spread, and the relative pace of each car throughout the race as a line gradient. The traces are calculated using cumulative race lap times, which are adjusted by the median lap time at that point in the race. The horizontal zero line represents a virtual reference car completing the average lap time of the field. The lines above this zero line depict faster cars, while the lines below it represent slower ones.

Here are some key features of the race traces:

• The line colors for each driver are based on their team colors.
• The fastest lap is marked with a ★.
• Laps where a car went via the pit lane are marked with a ●.
• Laps affected by the safety car are highlighted in yellow, indicating why the gaps between cars have reduced.
• Overtakes are visible where the lines cross, often due to pit-stops.
• Truncated lines indicate retirement from the race.

The shadow at the bottom of the trace indicates which cars have been lapped by the lead car. This helps to reveal some effects, such as leaders making pit-stops to avoid slower traffic ahead. Backmarkers must allow leading cars through, and the edge of the shadow shows why their lines suddenly dip. Leaders may also ease off to let a lapped car through at the end of a race.

It's worth noting that good safety car data is hard to find, and the data scraped from Wikipedia may contain some mistakes. Therefore, the virtual safety car highlights in the traces are the author's estimates using lap-time data.

Overall, these race traces offer a comprehensive and informative way to understand the progress of each F1 race in 2011.

2011 Formula One World Championship¶

For background see Wikipedia; here's an excerpt:

The 2011 FIA Formula One World Championship was the 65th season of FIA Formula One motor racing. The original calendar for the 2011 Formula One World Championship consisted of twenty rounds, including the inaugural running of the Indian Grand Prix before the cancellation of the Bahrain Grand Prix. Pirelli returned to the sport as tyre supplier for all teams, taking over from Bridgestone, marking their return to Formula One for the first time since the 1991 season. Red Bull Racing was the reigning Constructors' Champion. Red Bull Racing's Sebastian Vettel was the defending Drivers' Champion, one of five World Champions appearing on the grid. Vettel won his second World Championship at the 2011 Japanese Grand Prix, becoming the youngest driver, at 24 years and 98 days, to do so. Red Bull Racing won the Constructors' Championship.
