A grid of 18 yellow smiley faces, each rendered as an SVG, demonstrates a React and D3 integration. The code uses `d3.range` to generate the array and `d3.arc` to create the mouth path, while each face’s eye size is randomly varied via `Math.random()`. The `FaceContainer` component, defined in `smiley.js`, combines a `BackgroundCircle` and positioned eye circles within a translated `<g>` element. This example shows how to build custom SVG components with React and D3’s shape generators.

Hello HTML

This example renders a grid of smiley faces using React components and D3’s arc generator. Each face consists of a yellow background circle, two black eyes, and a mouth drawn with `d3.arc()`, all composed inside an SVG via a shared `FaceContainer` that applies a translation transform. Fifty faces are generated with randomly varying eye radii, producing subtle visual differences. The code demonstrates component reuse, D3’s `arc` API for path generation, and React’s rendering of SVG elements.

Hello HTML

A grid of eighteen SVG smiley faces, each generated with randomized facial features, fills the canvas. The example demonstrates composing reusable React components to build a data visualization from primitive shapes. Using D3's `arc` generator, it constructs the mouth as an arc path, while circles form the eyes and background. The React app maps over a D3 `range` array to render the faces, with random values for stroke width, eye placement, and mouth radius applied to each instance.

Hello HTML! Smiley Face

A grid of randomly generated smiley faces fills the screen, each rendered as an SVG via React components. The code uses D3's `arc` generator to create the mouths and `range` to produce 18 faces, with randomized properties for stroke width, eye size and offset, and mouth dimensions. The example demonstrates composing reusable React components for SVG visualization, leveraging React 18 and D3 v7 within an HTML page.

A grid of eighteen identical smiley faces is rendered, each composed of a yellow circle with black eyes and a mouth drawn as a half-circle arc. The faces vary randomly in eye radius due to `Math.random()` calls on each render. Built with React and D3, the `Face` component composes reusable subcomponents like `BackgroundCircle`, `Eyes`, and `Mouth`, which uses `d3.arc` to generate the mouth path. All shapes are drawn as SVG elements within a transformed `<g>` group, centered per face.

Smiley Face

A grid of fifteen smiley faces renders in SVG with React, each face composed of a yellow circle, two eyes, and a mouth. The code builds each face from reusable components: `BackGroundCircle`, `Eyes`, `Mouth`, and `FaceContainer`, with the mouth drawn using d3’s `arc()` generator. Each face’s eye radius and mouth width are randomized using `Math.random()`, creating slight variations across the identical grid layout. The React components are mounted via `ReactDOM.render`, and the overall structure is positioned using SVG group transforms.

Hello HTML

A grid of eighteen identical smiley faces, each rendered as a yellow circle with black outline, two eyes, and a curved mouth, is displayed. The example demonstrates how to build a reusable React component hierarchy using JSX and SVG. It uses ReactDOM to render the faces, with D3's `arc` generator defining the mouth shape and `range` from D3 producing the grid.

Hello HTML

A collection of smiley faces is rendered as SVG elements using React components. Each face is composed of a yellow background circle, two eyes, and an arc-shaped mouth, with positions and sizes randomized through JavaScript's `Math.random`. The face geometry is assembled from modular React components, while D3's `arc` generator creates the mouth path. The example demonstrates a React and D3 integration, with 18 faces generated using D3's `range` function.

Hello HTML

A grid of 32 tiny smiley faces fills the viewport. Each face is an SVG assembled from React components for the yellow background circle, black eyes, and a mouth arc, with randomized eye sizes. The code uses React 18.2 to render SVG, and d3.v7’s `range` and `arc` functions to generate the grid and mouth path geometry. The mouth is drawn as a half-circle arc, leaving each face seemingly halfway through a smile.
