Let's make a face with D3.js!

This example uses D3.js to build a smiley face whose eyebrows animate. The code selects an SVG element, sizes it to the full browser window, and appends a rounded rectangle as the background. It demonstrates fundamental DOM manipulation by chaining D3 methods like `select` and `append` to create the face’s parts, with the eyebrow movement driven by simple data-driven updates in the same SVG structure. The project relies on D3 v5 and renders entirely as SVG.

A D3.js tutorial demonstrates fundamental DOM manipulation by building a smiley face with animated eyebrows in an SVG canvas. Using D3's `select` and `append` methods, the code creates and styles SVG circles and other elements dynamically. The example relies on D3 v5's modular imports and shows how to set attributes like radius and position through chained method calls. The accompanying video explains the step-by-step process, while the working code is rendered directly in the browser using standard SVG elements within a 960×500 viewport.

This example creates an animated smiley face using D3.js, with eyebrows that move to demonstrate fundamental DOM manipulation. The visualization builds the face from SVG elements, including eyes, a mouth, and interactive eyebrows. The code imports specific D3 modules such as `select`, `arc`, and `scaleLinear` to construct the face and manage its components. While the primary focus is the face, the code also includes a bar chart with telescope data, mapped using `scaleBand` and `axisBottom`, though this chart is not the main visual output. The face itself is rendered entirely through SVG.

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face whose eyebrows animate. The visualization loads population data from a CSV file using `d3.csv`, though the data itself does not drive the face’s rendering. The face is drawn entirely with SVG elements selected and appended via `d3.select` and standard DOM methods. The eyebrows move through D3’s selection and transition APIs, highlighting how D3 can directly manipulate existing SVG nodes without data joins or scales. The page uses D3 v5 and renders all graphics in a single SVG container.
