Dash: data exploration web apps in pure Python

on YouTube ↗41m

" summary

Claim: build interactive data-exploration web apps in pure Python using Dash, built on plotly.js, Flask and React, with callbacks that allow multiple inputs but one output per callback. Demonstrations include a recently released data table (alpha, shipped two weeks earlier, TypeScript internals), live-updating Interval graphs, an image-processing demo using Pillow, Gapminder-driven examples, deploys on Heroku, and real apps split across five to ten Python files.
