This example renders a smiley face as an SVG graphic using React for component structure and D3’s `arc` generator to create the mouth. The face consists of a yellow circle with a black stroke, two eye circles, and a mouth path drawn via an arc with specified inner and outer radii and angular spans. D3 v5 and React 16.9 are loaded from CDNs, with the SVG output centered and scaled to a 960×500 viewport. The code defines all geometric parameters as constants, making the layout explicit and easily adjustable.

d3 test

This example renders a smiley face as a static SVG graphic using React and D3’s `arc` generator. A yellow background circle is drawn with a black stroke, and two black eye circles are placed symmetrically on either side of the face’s vertical center. A mouth path is created by the D3 arc, which defines a half-ellipse from a start angle of -π/2 to +π/2, positioned near the bottom-right of the canvas. The code uses React functional components, D3’s `arc()` for the mouth’s path, and SVG elements for circles and paths.

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.

Hello HTML

This example renders a smiley face using React and D3’s `arc` function. The SVG contains a yellow circle for the face, two black eyes positioned via offset constants, and a mouth drawn as an arc path with `d3.arc()`. The code defines a React component that returns SVG elements, with sizes and coordinates computed from fixed width and height values. It demonstrates combining React’s declarative JSX with D3’s geometry utilities inside an SVG rendering, using d3.v6 and React 17.

smiley face

This example renders a classic smiley face as an SVG graphic using React components and D3’s `arc` generator. The face consists of a yellow circle for the head, two black circles for eyes positioned symmetrically via `eyeOffsetX` and `eyeOffsetY`, and a curved path for the mouth created with `arc().innerRadius(90).outerRadius(100)` spanning from PI/2 to 3PI/2. All shapes are centered using a `<g>` transform, with the head’s radius calculated from the viewport height minus stroke width. The code imports `arc` from D3 v7 and uses ReactDOM to mount the SVG into the page.

d3_react

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.

smile face with react

This example renders a smiling face as an SVG graphic using React components and D3’s `arc` generator for the mouth. The face consists of a yellow circle, two black eyes with white highlights, a curved mouth path, and additional gold and white elliptical details, all positioned via SVG transforms. D3 v7 provides the arc shape, while React 17 manages the component hierarchy. The drawing is static, with dimensions and offsets hardcoded in JavaScript, and rendered into the DOM via `ReactDOM.render`.

This example shows a simple smiley face rendered as an SVG using React components for structure and D3’s `arc` function to generate the mouth path. The face is centered with a yellow circle, two black eye circles, and a crescent-shaped mouth created via `d3.arc` with defined inner and outer radii and angular extents. Positioned offsets for the eyes and stroke width for the face outline are computed dynamically. The code integrates React 16.9 and D3 v5, rendering directly into the DOM via `ReactDOM.render`.

SVG

This example renders a smiley face using React and D3, composed of SVG circles and an arc path. The face includes a yellow background circle with a black stroke, two eyes positioned symmetrically, and a mouth created with d3.arc(). The code uses React components for the background and eyes, while a D3 arc generator computes the mouth’s path with specified inner and outer radii and angles. The visualization is static, with all elements centered within an 960×500 SVG canvas.
