Add interactive GitHub Pages demo

[fraserxu]

What changed

• add a dependency-light interactive demo under docs/
• load the published react-chartist 1.0 package with React 19 and Chartist 1.5
• demonstrate Line, Bar, and Pie chart recreation plus in-place data updates
• add responsive, accessible styling and link the live demo from the README

Why

The existing gh-pages site is a broken legacy bundle from the pre-1.0 project. Keeping the demo as static files under master/docs makes the Pages deployment easy to inspect and avoids another build toolchain.

Validation

• npm run check
• Line, Bar, and Pie interactions verified in a browser
• data update verified by SVG path change
• mobile layout verified at 390px with no horizontal overflow

Note

Low Risk
Documentation and static demo assets only; no library runtime or API changes.

Overview
Replaces the broken legacy gh-pages experience with a static, build-free demo in docs/ for GitHub Pages, and links it from the README.

The demo loads react-chartist 1.0, React 19, and Chartist 1.5 via an import map (esm.sh), with docs/.nojekyll so Jekyll does not interfere. docs/demo.js drives an interactive workbench: switch Line / Bar / Pie, update data in place, and surface Chartist created events in a live readout. docs/style.css adds landing-page layout, chart theming, focus styles, and responsive breakpoints.

No changes to the published library package—only docs and the README demo link.

Pie chart wrong aria label

Medium Severity

The ChartistGraph aria-label always says the chart shows a seven-day sample. In Pie mode the data is three product categories, not weekdays, so assistive technologies announce a misleading description when users switch to Pie.
