This directory contains code to scrape and parse the Advent of Code daily leaderboards into a Pandas data frame, and some Altair plots that hope to put contest puzzles into the historical context.
The time.one and time.two plots are straightforward box plots of the time it
took the first 100 people to get the first or both stars, respectively. The
endpoints of the rule show the times used by the first and the 100th rank, and
the edges of the box show the 25th and the 75th rank.
The twistiness of a puzzle can be measured by comparing how long it took the general public to get both stars, compared to just the first one.
The twist plot shows this as a similar grouped bar chart as the leaderboard
time plots, while the twist.heat plot uses a heat map. The latter is better
for overall comparisons, especially across years. The former is better if you're
interested in the exact twistiness values.
The specific metric used here is based on the total time used by all 100 leaderboard ranks to get one or two stars; the metric is simply the ratio of the latter and the former. This means it's never below one.
