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.

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

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

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

A set of yellow smiley faces is rendered across the screen. Each face is a composite of SVG circles and a path for the mouth, whose arc is generated using the `arc` function from the d3 library. The React code in `index.js` creates 18 faces, each with random properties for stroke width, eye offset and radius, and mouth dimensions. The entire composition is generated through React components and rendered into an SVG canvas.

Hello HTML

This example renders a grid of smiley faces, each generated procedurally with randomized facial features. The code uses React components to compose SVG elements like circles and paths, while the D3 `arc` function creates each mouth. It demonstrates how to build reusable, nested visualization components with React and D3 together, rendering 18 distinct faces as SVG output.

Hello HTML

A grid of 690 randomly generated smiley faces fills the viewport, each rendered as an SVG composition of a yellow circle, two eyes, and a curved mouth. The example demonstrates React component composition, where each face is built from reusable components for the background, eyes, mouth, and container. It uses the D3.js arc generator to construct mouth paths and ReactDOM to render the array of faces, with randomized stroke widths, eye offsets, eye radii, and mouth dimensions creating variation across the grid.
