Viz clj - Clojure data visualization for beginners

on YouTube ↗15m

" summary

Viz clj is a beginner-focused Clojure plotting library that builds Vega-Lite specs via Hanami by generating maps from a simple pipeline syntax and accepting files, web URLs, tablecloth datasets or sequences of maps; it auto-detects x/y columns, accepts keywords, and exposes hanami substitutions plus direct Vega-Lite tuning. Computation for histograms and regression currently runs on the Clojure backend (reducing payload); layers, log transforms, and a regression-line generator are supported or planned. Error handling uses a macro to strip stack traces and show concise messages; docs combine Codox API pages and tutorial notebooks.
