Data Visualization cheatsheet, plus Spanish translations

Recently, Rich and I were poking around transit data, and we were struck by the amount of structuring that goes into transit timetables. For example, consider this weekend rail schedule table from SEPTA, Philadelphia’s transit agency. Notice these big pieces: The vertical text on the left indicating trains are traveling “TO CENTER CITY”. The blue header, and spanner columns (“Services” and “Train Number”) grouping related columns. The striped background for easier reading. Also the black background indicating stations in Center City (the urban core). Tables like this often have to be created in tools like Illustrator, and updated by hand. At the same time, when agencies automate table creation, they often sacrifice a lot of the assistive features and helpful affordances of the table.
