Smiley Face Part 6

A grid of 18 randomly parameterized smiley faces demonstrates component reuse in React with SVG rendering. Each face reuses the same `Face`, `BackgroundCircle`, `Eyes`, and `Mouth` components, while the D3 `arc` helper generates the mouth path. Randomized values for stroke width, eye offset, eye radius, mouth width, and mouth radius create visual variety across the grid. The `FaceContainer` wraps each face in a translated SVG group, combining React's declarative composition with D3's geometry utilities.

Smiley Face Part 5

A React application renders a smiley face as an SVG, composed of a yellow background circle, two black eyes, and a D3-generated mouth arc. The top-level `index.js` assembles these components, passing numeric values for radii and offsets. The D3 `arc` API constructs the mouth path, while React Fragments in `Eyes.js` group the two eye circles without extra markup. The design splits components across separate files, demonstrating modular React structure with ES6 imports.

Smiley Face Part 4

This example draws a yellow smiley face with black outlines using React and D3. It positions two eyes and an arc-shaped mouth relative to a centered background circle, all rendered as SVG elements. The React component builds the graphic declaratively, while D3’s `arc` API generates the mouth path with specified inner radius, width, and angular range. The code defines fixed constants for sizing and offsets, producing a static face without interaction.

Smiley Face Part 3

This example demonstrates how to draw a smiley face using React and D3. It renders a yellow circle with black stroke for the face, two black eyes, and a mouth created with the `d3.arc()` path generator. The SVG elements are positioned using a centered `<g>` transform, with eye and mouth coordinates computed from fixed offsets and radii. The code uses React 16.9, D3 v5, and renders to SVG.

Smiley Face Part 2

This example displays a classic yellow smiley face that fills the browser window, with two black eyes and a wide, friendly grin. The face is rendered as an SVG using React and ReactDOM, with the component structure defining circles for the head and eyes. The face’s size and position are calculated dynamically from the window’s inner dimensions, centering it precisely on the screen. The code leverages React’s declarative JSX syntax to create the SVG elements, with a `<g>` transform handling the central translation.

Smiley Face Part 1

A static SVG visualization depicts a yellow smiley face as a single large circle with two smaller black circles for eyes, drawn on a 960×500 canvas. The main face uses a filled circle with a thick black stroke, while the eyes are unfilled circles positioned symmetrically around the center. The code directly creates three `<circle>` elements in HTML, specifying coordinates, radii, and fill/stroke attributes. This example demonstrates basic SVG shapes and attributes without any JavaScript libraries or data sources.
