Fork of React Starter

A choropleth map of world countries colors each nation by continent using a D3 geo path generator and a color scale. The visualization renders as an SVG globe inside a React component built with React hooks, fetching geographic data from the World Atlas TopoJSON and TSV files. Hovering reveals country names and indices appended as SVG title elements, while a transparent sphere outline frames the map. The code leverages d3.json, d3.tsv, and d3.geoPath to construct the projection and interactivity.

This interactive map displays country boundaries with colors representing continents, using an orthographic projection that rotates as the user drags the globe. The visualization loads world-atlas data from TSV and TopoJSON files, then fixes specific country discrepancies before rendering. It uses `d3.geoPath`, `d3.geoOrthographic`, `d3.zoom`, and `d3.drag` for interaction, with continent colors assigned via `d3.scaleOrdinal` from the Tableau10 scheme. Hovering highlights a country in red, while the title element shows the country name and index.

Fork of Cheap Tricks for Interaction

This fork of the "Cheap Tricks for Interaction" example displays world countries on an orthographic projection, colored by continent using an ordinal color scale. The map is built with `d3.geoPath` and data from `world-atlas`, with country names from a matching TSV file. A custom drag interaction, implemented via `d3.drag`, allows users to move a temporary green rectangle across the screen, while the underlying sphere rotation code remains commented out.

Fork of D3 Starter

This is a minimal demonstration of starting a D3 project, showing the text “Hello D3 version 7” centered in the browser window. It uses D3 v7’s `select` method to target the `body` element and set its text content, with the page layout styled via plain CSS. The example serves as a bare-bones template, loading D3 from a CDN and relying on a separate `bundle.js` file for the main script, as outlined in its accompanying README.

Fork of React Starter

This example renders a full-screen “Hello React!” message in large, centered type. It demonstrates a minimal React application setup using `createRoot` from `react-dom` to mount the root component into `index.html`. The app imports React 18.2.0 from a UMD bundle, defines a stateless functional component, and renders it into the DOM. There is no data source or chart; the example focuses on boilerplate structure for React-based visualizations.
