Smiley Face Part V

This example renders a classic yellow smiley face in an SVG canvas using React components. The visualization is built from three modular React files—`BackgroundCircle`, `Eyes`, and `Mouth`—that are composed within a single `<svg>` element. It uses React fragments to group multiple eye circles without extra DOM nodes, and leverages the D3.js `arc` API to draw a mouth as a semicircular path with a defined inner and outer radius. All elements are positioned relative to the canvas center via an SVG `<g>` transform, with fixed pixel dimensions for the face, eyes, and stroke width.

Smiley Face Part IV

This example shows a classic smiley face constructed with SVG shapes and rendered through React. A yellow background circle with a thick black stroke forms the head, while two black circles serve as eyes and an arc path creates the mouth. The code uses React components and hooks into D3’s `arc` generator from the `d3` module to compute the mouth’s path coordinates. The visualization is fully static, with dimensions fixed at 960 by 500 pixels, and demonstrates a simple integration of D3 geometry with React’s declarative rendering in an SVG container.

Smiley Face Part III

This interactive example renders a simple smiley face as an SVG graphic, constructed using React components and D3.js shape primitives. A yellow circle forms the head, with two smaller black circles for eyes and a D3 arc path defining the mouth’s curved smile. The composition is built by importing the `arc` function from D3, which generates the mouth’s path data based on configured inner and outer radii and angular start and end points. All elements are positioned relative to a central coordinate system using SVG transforms, with React handling the declarative markup and DOM rendering.

Let's Make a Face Part I

This example shows a partially constructed smiley face rendered as an SVG graphic. A large blue circle forms the head with a black stroke, while two larger white-ringed circles represent the eye sockets, each containing a small white filled circle for the pupil. The face is drawn directly using SVG elements within an HTML page, positioning each circle with explicit `cx`, `cy`, and `r` attributes. The rendering relies on the browser’s native SVG support, with no JavaScript libraries or data sources involved.

Hello HTML

This example demonstrates the simplest possible HTML page, rendering the text “Hello World!” as a top-level heading. It uses only standard HTML elements—`<!DOCTYPE html>`, `<html>`, `<head>`, `<title>`, and `<body>`—with no external libraries, CSS, or JavaScript. The page’s content is static markup, making it a minimal starting point for web-based visualization projects. The rendering approach relies entirely on the browser’s default HTML parsing and layout engine, with no data bindings or interactive behaviors present.
