Smile face

This example renders a yellow smiley face in an SVG using React and D3. The face is composed of a background circle, two eyes, and a mouth, all positioned relative to a center point. The mouth path is generated with the D3 `arc()` function, which creates a curved shape based on specified radii and angles. The React components structure the SVG elements, while D3 handles the geometric calculations for the mouth's arc. The illustration demonstrates a simple, modular approach to building shapes with reusable React components.

D3 with React

A bright yellow smiley face drawn with SVG primitives renders inside a React component. The face uses layered `<circle>` elements: a large yellow head with a black stroke, two black-outlined eyes, and a mouth defined by a D3 `arc()` path generator. The D3 arc is set with specific inner and outer radii and start/end angles to create a curved mouth shape. The example demonstrates integrating D3’s path-generation utilities with React’s declarative rendering, where D3 computes geometry and React outputs the SVG.

React and SVG with D3

This example shows a yellow smiley face drawn as an SVG graphic, built with React components and D3’s arc generator for the mouth. The face includes a circular head, two eyes, and a curved mouth, all positioned using D3’s arc function with specified inner and outer radii and start/end angles. React renders the SVG elements declaratively, while D3 (v5) computes the path data for the mouth arc. The code uses `ReactDOM.render` to mount the app and D3’s `arc()` API to define the mouth’s shape.

smiley face

This example renders a yellow smiley face using React and D3.js. It draws a face with a circle head, two eyes, and a curved mouth via an SVG path. The shape is constructed with D3’s `arc` generator for the mouth, while circles handle the head and eyes. Fixed numeric constants define offsets, radii, and stroke width, and the entire composition is centered inside a 960 by 500 SVG canvas.

Smile face in React and d3

This example renders a yellow smiley face as a static SVG graphic using React and d3. The composition combines a large yellow circle for the face, two smaller circles for eyes, and an arc path for the mouth, all centered within a 960×500 viewport. The code constructs the mouth with `d3.arc()`, using specified inner and outer radii and angular start/end points. React manages the DOM rendering through `createRoot`, while d3.v7 provides the arc generator and SVG elements are declared directly via JSX.

D3 and React Smiley

This example shows a smiley face composed of SVG shapes, with a yellow circular background, two black eyes, and an arc-shaped mouth. The face is built from reusable React components—BackgroundCircle, Eyes, and Mouth—assembled within a FaceContainer that wraps the SVG and applies a translation to center the graphic. The mouth uses the d3.arc() API to generate an SVG path with specified inner and outer radii and angular extents, while the overall layout is positioned using React props passed from the top-level App component.

This example shows a classic smiley face rendered as a static SVG graphic, using React to define the component structure and D3’s `arc` generator to create the mouth path. The face consists of a yellow circle with a black stroke, two eye circles positioned symmetrically, and a mouth arc drawn from the `arc()` helper with specified inner and outer radii and angular ranges. React handles the JSX elements for the SVG, while D3 computes the complex path geometry. All dimensions and offsets are hardcoded, and the graphic is centered within a 960×500 viewport.

Smily Face

This example renders a smiling face using React and D3’s `arc` generator to create the mouth as a path. The SVG contains a yellow circle with a black stroke, two eyes as plain circles, and the curved mouth arc. React manages the component structure and JSX, while D3 computes the mouth’s path geometry with specified start and end angles. The face is centered via a translate transform, and hardcoded constants define dimensions and positions.
