Rethinking Data Visulisation with PyScript
summary
Claim: run Python in the browser as a usable data‑science platform. Implementation: Pyodide via WASM underlies PyScript, with a pyenv YAML loader, micropip and wheel‑by‑URL installs, and DOM bridging. Demonstrations: matplotlib (HTML5 backend), folium maps, Bokeh + Panel dashboard with widgets, hvplot and Altair, and scikit‑learn workarounds (t‑SNE needs dtype/PCA trick); UMAP fails because numba isn’t in Pyodide yet. Status: alpha, usable for client‑side demos but hit by load time, memory and performance limits.
