Hello HTML

Hello HTML

A grid of randomized smiley faces renders as SVG via React components, with each face composed of a yellow background circle, two eyes, and an arc-based mouth. The React app maps over a range of indices from d3.range to generate 18 faces, each with randomized properties for stroke width, eye position and radius, and mouth dimensions. The d3.arc API constructs the mouth path, while React Fragments avoid extra DOM nodes for the eye pairs. The rendering uses d3.v7 and React 17, with each SVG face centered within a 160-pixel viewport.

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 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.

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 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 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

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

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.
