A React component renders a yellow smiley face as a scalable vector graphic, composed of a circular background, two eyes, and a smiling mouth. The face is built from separate functional components—`BackgroundCircle`, `Eyes`, `Mouth`, and `FaceContainer`—that accept numeric props for dimensions and positioning. The mouth uses the `d3.arc` generator from d3.v6 to create a semicircular path, while all elements are centered within an SVG container via a translation transform. The example demonstrates how to structure reusable, data-driven visual components with React and D3.

Smiley Refactored

This example displays a yellow smiley face with black-outlined circular eyes and a curved mouth, centered on a blank canvas. It demonstrates component-based visualization with React, breaking the face into separate modules like `BackgroundCircle`, `Eyes`, `Mouth`, and `FaceContainer`. The code uses d3’s `arc` API to generate the mouth path, while React components pass numeric props for positioning and sizing. The face is rendered as SVG elements within a translated `<g>` group, with fixed dimensions of 960 by 500 pixels.

Refactor of My Smiley Face

A yellow smiley face rendered with SVG components in React, featuring two eyes, red cheeks, and a mouth drawn as an arc. The face is centered using a translated group element, with all shapes positioned relative to that center. The code imports `arc` and `line` from d3, using `arc` to generate the mouth path with specified inner and outer radii and angles. Static circle elements define the eyes and cheeks, while React functional components structure the SVG markup. The visualization demonstrates a refactored approach to assembling a simple figure with reusable, declarative components.

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 Part I

A reusable React component renders a yellow smiley face with black circular eyes and a curved mouth using SVG. The face is composed of separate components for the background circle, eyes, and mouth, assembled inside a centered SVG group. D3's `arc` generator creates the mouth path, while React props control dimensions like eye offset, radius, and stroke width. The example demonstrates modular component composition with D3 integration in React.

smiley face refactoring into react components

This example displays a smiley face built from a yellow circle, two eyes, and a curved mouth, rendered as SVG. The code refactors drawing primitives into named React components like `BackgroundCircle`, `Eyes`, and `Mouth`, with `Face` orchestrating their layout and `FaceContainer` providing the SVG canvas. It uses React for component composition and d3’s `arc` function to generate the mouth’s path. Properties such as eye offset and mouth radius are passed as parameters, enabling flexible geometry without hard-coded coordinates.

Smiley Face React

This example shows a yellow smiley face built from modular React components, with circular eyes and an arc-based mouth positioned on a yellow background circle. The face is centered within an SVG canvas using a translated group, and each facial feature is defined as a separate React component. The code uses D3’s `arc` API to generate the mouth path, while React handles the component hierarchy and props for sizing and positioning. All rendering is SVG-based, with the face drawn from hardcoded dimensions passed as props.

Smiley Face Pt. I

A smiling face rendered in yellow SVG using React components. The face is composed of a background circle, two eyes, and a mouth, all positioned relative to the center of a 960 by 500 viewport. The mouth is drawn using the d3.arc generator with specified inner and outer radii and angular range. This example demonstrates the composition of reusable React components for scalable vector graphics.

Smiley face with react comp

A React component renders a smiley face as an SVG graphic, composed of a yellow circle with a black outline, two eyes, and an arc-shaped mouth. The face is centered on a 960 by 500 canvas using a group translation. The mouth is generated with d3.arc, which defines its inner and outer radii and angular extent. The code defines reusable React components for the background, eyes, and mouth, passing positioning and sizing values as props. The illustration uses React 17 and d3 v6, displaying the rendering approach of combining React’s component model with D3’s geometry API.
