Let's Make a Face with D3.js!

This example demonstrates how to build a stylized face using D3.js version 5 within a React framework, rendering to an SVG element with a red background. The visualization uses D3’s selection and style methods to manipulate the SVG canvas, applying a solid background color via `svg.style`. The code initializes an SVG of fixed dimensions and uses D3’s core API to set the visual styling, showing a minimal yet interactive approach to creating geometric compositions. The face itself is not yet drawn, focusing instead on the foundational setup for future SVG-based rendering.

React Starter

This React starter example renders a simple, large centered text message reading "React Starter" directly into the DOM. It demonstrates the basic integration of React 16.10 with a minimal HTML page, using `ReactDOM` to mount a component into a `#root` div. The example relies on the production builds of React and ReactDOM loaded from the unpkg CDN, with the application logic defined in a separate bundled JavaScript file. No data visualization or external dataset is involved; it serves purely as a scaffold for building interactive React-based visualizations.

Untitled

This example demonstrates an interactive 3D globe visualization built with React and D3. It renders a rotating Earth using `d3.geoOrthographic` and `d3.geoPath` to project country boundaries onto a canvas, with atmospheric shading applied through layered gradients. The code uses `d3.forceSimulation` to position label nodes around the planet, enabling smooth hover interactions that display country names and associated data. The visualization loads geographic coordinates from a bundled TopoJSON dataset and updates the globe’s rotation via a requestAnimationFrame loop, providing a dynamic and responsive exploration of world geography.

Cars Report

This example displays a text-based report of affordable used cars, showing only the entries with a price under $2,000. It filters an embedded JavaScript array of car objects and formats each matching record into a single line containing the year, make, model, and price. The filtered results are joined with newlines and rendered inside a large `<pre>` element using the DOM API via `getElementById`. The code relies on standard JavaScript array methods, such as `filter`, `map`, and `join`, alongside the `formatCar` function for string composition, with the data and logic running entirely in the browser.

Cars Report

This example displays a single car make, "Honda," in a large preformatted text element, representing a minimal dynamic report. It loads car data from a local JSON array defined in `cars.js`, which contains fields for year, make, model, and price of five vehicles. The React application uses `index.js` to import that array, access the first record’s `make` property, and update the DOM via `document.getElementById`, rendering static text without any charting or interaction. The code relies on React’s component structure and the standard browser DOM API for output.
