Let's make a Face with D3.js!!!

This example uses D3.js v5 to draw a smiling face in an SVG, composed of a yellow circle, two eyes, animated eyebrows, and a mouth path. The face is centered in a 960x500 canvas, with the mouth created using the `arc` function to generate a curved path. Eyebrows are rectangles that animate up and down via chained `.transition()` calls, each lasting 2000 milliseconds. The code relies on D3’s selection and shape-generation APIs, with the SVG created in the HTML file and styling handled by an external stylesheet.

Let's make a Face with D3.js!!!

This example uses D3.js to construct a smiling face from basic SVG shapes, including a yellow circle head, two eyes, animated eyebrows, and an arc-based mouth. The code imports `select` and `arc` from D3, appends shapes to an SVG canvas, and applies chained transitions to the eyebrows to make them move up and down over two-second intervals. The visualization renders entirely in SVG and demonstrates D3’s ability to create and animate custom graphics without external data, relying instead on hardcoded coordinates and dimensions.

Hello VizHub

This example demonstrates a minimal D3.js visualization that renders a simple text message onto a webpage, serving as an introductory template for VizHub projects. It uses D3’s `select` method to target a div element with the ID `message` and sets its text content to a static string imported from a local ES6 module. The page is styled with a custom CSS file and the Ubuntu font fetched from Google Fonts. The code includes an HTML shell, a separate JavaScript file for the message, and D3 v5 loaded via CDN.

Hello VizHub

This example demonstrates a minimal D3.js visualization that displays a static text message, “Hello VizHub!”, centered on a dark blue background. It shows how to structure a basic web page with an HTML container, a separate stylesheet for typography and color, and modular JavaScript files. The code uses D3’s `select` function to set the text content of a `div` element, while an ES6 module exports the message string. Styling relies on the Ubuntu font from Google Fonts, applied via CSS.
