Smiley Face React & D3

Smiley with React & D3

This example shows a classic smiley face rendered as an SVG graphic, centered on a 960×500 canvas. The face consists of a yellow circle with a black stroke, two eyes, and an arc-shaped mouth. The visualization is built using React to manage the SVG elements, while D3’s `arc` function generates the mouth’s path data by specifying inner and outer radii and angular start and end points. All shapes are declared declaratively within the React component and rendered via `ReactDom.render`.

Smilie Face with React and D3

This example shows a classic smiley face rendered as an SVG graphic, with a yellow circular head, two black eyes, and a curved mouth. The face is built using React components that return SVG elements, while D3’s `arc` generator defines the mouth’s path. The code sets fixed dimensions and coordinates for the face’s features, then uses ReactDOM to mount the component. Both React and D3 are loaded via UMD scripts, and the rendering relies purely on static D3 shapes without any data or interaction.

Smiley Face with JS and React

This example renders a classic smiley face as a React component, using SVG for display. It builds the face from primitive shapes: a yellow circle for the head, black-stroked eyes, and a mouth drawn with the D3 `arc` generator. The D3 arc creates a semicircular path by specifying inner and outer radii, a stroke width, and start/end angles, while React manages the SVG elements and JSX markup. The visualization demonstrates a minimal integration of D3’s geometry utilities with React’s declarative rendering in a static, non-interactive diagram.

Smiley Face (React & D3)

A React component renders a smiley face as scalable vector graphics (SVG), composed of a yellow background circle, two dark eyes, and a curved mouth. The face is assembled from reusable components—BackgroundCircle, Eyes, Mouth, and FaceContainer—which accept props for positioning and sizing. The mouth path is generated using D3’s `arc()` generator with specified inner and outer radii and angles, while the overall layout is centered via SVG transforms. The example demonstrates integrating D3 for geometry generation within a React component structure.

Smiley Face

This example uses the React framework to construct a smiley face as an SVG graphic. The visualization is built from three modular components: a yellow background circle, two eyes, and a mouth. The mouth is generated using the `d3.arc()` API to create a path with a specified inner and outer radius. The face is centered within an 960 by 500 pixel SVG canvas using a translation transform. The code demonstrates how React components and D3's path generation can be combined for simple, declarative graphics.

D3/React: Smiley Face

Built with React and D3 v7, this example renders a smiley face as an SVG. The code defines a React component that uses D3's `arc()` function to generate a mouth path with specified inner and outer radii, and defines circles for the face and eyes. The face and features are positioned using shared constants for width, height, and offsets. The component renders directly into the DOM via ReactDOM. The visualization demonstrates a hybrid approach, combining React's declarative markup with D3's geometry utilities for generating SVG paths.

Smiley Face with React

A modular React application renders a grid of smiley faces, each composed of scalable vector graphics circles and a D3 arc path. The Face component composes BackgroundCircle, Eyes, and Mouth subcomponents within a FaceContainer that establishes the SVG coordinate system. D3’s `arc()` generator creates the mouth shape with configurable inner radius, outer radius, and start/end angles. The main app maps over a D3 `range(5)` array to produce multiple face instances, but each iteration actually renders two overlapping faces with randomized eye radii and mouth widths, demonstrating reusable component properties and the integration of React JSX with D3-generated SVG paths.

Smiley Face w/ React

A grid of 18 randomly generated smiley faces demonstrates how React components can be composed with D3-generated SVG paths. Each face uses reusable React components for the face, eyes, mouth, and teeth, with randomized properties like eye radius, mouth width, and teeth position. The mouth is drawn using `d3.arc()` to create a variable-width smile path, while all other shapes are plain SVG elements. The example combines React's component model with D3's arc generator to produce varied, data-driven visual output.
