Fun with smiley face

Smiley Face

This example uses the React framework to construct a smiley face as an SVG graphic. The visualization is built from three modular components: a yellow background circle, two eyes, and a mouth. The mouth is generated using the `d3.arc()` API to create a path with a specified inner and outer radius. The face is centered within an 960 by 500 pixel SVG canvas using a translation transform. The code demonstrates how React components and D3's path generation can be combined for simple, declarative graphics.

Smiley Face Part 1

This example shows a basic smiley face constructed from a yellow circle with two red eyes and a black outline, rendered as an SVG graphic. It draws the face using React components that output SVG elements, with a D3 arc generator imported but not yet applied to create a mouth. The code positions the head and eyes using SVG circle elements with a fixed stroke width, while the face is centered on a 960 by 500 canvas. The d3.arc() function is referenced but commented out, leaving the mouth unfinished.

This example shows a simple, stylized smiley face rendered as an SVG graphic using React components. The face consists of a yellow circular background with a black stroke, two black eye circles positioned symmetrically, and a curved mouth created with a D3 arc generator. The code imports `arc` from D3 v5 to define the mouth’s path, while React components like `FaceContainer`, `BackgroundCircle`, `Eyes`, and `Mouth` assemble the visual elements. All shapes are drawn declaratively with SVG elements, and the face is centered within a 960 by 500 pixel viewport.

Smiley Face

A yellow smiley face rendered with React and D3 occupies a fixed 960 by 500 SVG canvas. The code builds the face manually using SVG circles for the head and eyes, and a D3 arc generator (`arc()`) with a `path` element to create the mouth. The face is centered with a group transform, and React manages the component structure using JSX. The example demonstrates simple, declarative SVG composition within a React component, using D3 solely for generating the arc path data.

Smile face

This example renders a yellow smiley face in an SVG using React and D3. The face is composed of a background circle, two eyes, and a mouth, all positioned relative to a center point. The mouth path is generated with the D3 `arc()` function, which creates a curved shape based on specified radii and angles. The React components structure the SVG elements, while D3 handles the geometric calculations for the mouth's arc. The illustration demonstrates a simple, modular approach to building shapes with reusable React components.

Smiley Face part 1

A yellow smiley face is rendered as an SVG graphic centered on a 960x500 canvas. The face consists of a yellow circle with a black stroke, two small black eyes, and a curved mouth created using the d3.arc() path generator. React manages the SVG elements, while D3 v7 provides the arc geometry for the mouth shape. The example demonstrates combining React components with D3 utilities for static, declarative visualization.

smiley face

This example renders a yellow smiley face using React and D3.js. It draws a face with a circle head, two eyes, and a curved mouth via an SVG path. The shape is constructed with D3’s `arc` generator for the mouth, while circles handle the head and eyes. Fixed numeric constants define offsets, radii, and stroke width, and the entire composition is centered inside a 960 by 500 SVG canvas.

Smiley

This example shows a cheerful smiley face rendered as a yellow circle with black outlines, featuring two eyes and a curved mouth centered on a 960×500 SVG canvas. The face is built using React components, with the background circle and eyes as SVG `<circle>` elements, while the mouth uses D3’s `d3.arc()` generator to create a path based on inner and outer radii and start/end angles. All elements are grouped and translated to the canvas center, with the mouth offset slightly via a transform.
