Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face from an SVG circle. Using the `select`, `append`, and `attr` methods from d3-selection, it sets the circle’s radius to half the SVG height and centers it via the `cx` and `cy` attributes. The code reads the SVG’s `height` and `width` attributes directly from the DOM, and runs against d3.v5 in a minimal HTML page with external styles defining the body margin and overflow. The face is static, with no interactive or animated features beyond the initial rendering.

This example demonstrates how to construct a smiley face using D3.js version 5, focusing on fundamental DOM manipulation with SVG elements. The code explicitly appends a group and a circle element to the SVG canvas, positioning them at the center of a 960×500 viewport. It uses the `select` and `append` methods from the `d3` namespace to build the geometric face outline, with a transparent fill and black stroke. The visualization is purely programmatic, with no external data source, and includes a static smile path defined directly in the HTML markup.

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from basic SVG shapes. The code selects the SVG element and appends a circle with a radius of 200 pixels, while the accompanying stylesheet hides body margins and overflow. Using D3 v5’s `select` and `append` methods, the visualization shows how to programmatically create and style SVG elements, with related video content explaining animated eyebrow movement.

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face in an SVG canvas. The code selects the `<svg>` element, retrieves its width and height attributes, and positions a circle at the center using those dimensions. It uses D3’s `select` method and chained attribute setters like `attr(‘r’)`, `attr(‘cx’)`, and `attr(‘cy’)` to control the face’s radius and coordinates. The rendering relies on D3 v5 with SVG output, and the accompanying video highlights interactive eyebrow movement.

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.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face from SVG shapes: a yellow circle for the head, two black circles for eyes, and an arc-generated mouth. The code uses D3 selections, `svg.append`, and the `arc` generator from the d3-shape module to construct the face. The face is static, with no interactive behavior or animations, and the rendering approach relies on SVG elements within a 960-by-500 viewport.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG shapes: a yellow circle for the head, two black circles for eyes, and a mouth drawn as a path. The code uses d3.select, d3.arc, and SVG attribute setters like .attr() to position elements on a 960x500 canvas. Static in this version, it serves as an introduction to D3’s data-driven approach, laying groundwork for an animated version where eyebrows move (per the README). The project runs on D3 v5 with SVG rendering.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG elements, including a polygon for the nose and animated eyebrows. It uses d3.select, append, and attr methods to build the face centered within an SVG canvas. The code imports the select and arc functions from D3 v5, and sets up a transformation group to position elements relative to the center of the 600×400 viewport. The result shows how D3’s data-driven approach can create simple, interactive graphics through direct SVG manipulation.
