The Financial Times' Visual Vocabulary names nine jobs a chart can do — flow, ranking, distribution, correlation, part-to-whole, change, magnitude, deviation, space. This atlas takes ten of the hardest forms in that vocabulary and builds each from raw SVG, on real numbers: 129,880 airline journeys and one analyst's study log. Every pixel hand-placed; every claim computed.
Because a chart library is an answer, and an analyst should first understand the question. Building a sankey's bezier links or a treemap's squarify pass by hand teaches what the form is — what it encodes, what it hides, where it breaks. After that, reaching for Power BI or d3 is a choice, not a crutch.
Forms follow the FT Visual Vocabulary taxonomy. Airline figures computed from the full public dataset (N=129,880). Study-log data is live from her daily ritual.
