This is a small charting page using D3.js to show the historical league positions of football clubs in the English leagues over time.

The build/ directory contains a Rakefile with instructions on creating the data. A small amount of this needs to be hand-edited (mapping team names to team IDs, for instance, and collecting data for the last few seasons) but the majority comes from the wonderful RSSSF. To build, here's the process I used:

1. in build, run bundle;
2. in build/, run bundle exec rake rsssf-seasons.json to pull the RSSSF data;
3. add extra files in TSV format to build/manual/ (see Rakefile for details);
4. run bundle exec rake add_tsvs[$dir];
5. bundle exec rake list_teams > teams.txt and add keys to any teams missing (nothing on the left-hand side of the =);
6. bundle exec rake list_tiers > tiers.txt, same again;
7. bundle exec rake football-league-positions.json historical-league-positions.csv for the final files to go into ext/.

There's no particular reason for its existence, I just wanted to see the rises and falls of teams like Swansea and Southampton in a graphical form!
