Smiley Face Part 1

Smiley Face Part 1

This example shows a yellow smiley face built from a background circle, two eyes, and an arc-shaped mouth, all rendered as SVG elements in a React component. The code uses D3’s `arc()` generator to create the mouth path, calculates the circle and eye positions from fixed numeric constants, and draws everything inside a `<g>` element translated to the center of an SVG canvas. React manages the component structure, while D3 v5 provides the arc geometry. The background circle is a separate React component that receives radius and stroke width as props.

This example shows a smiling face constructed from basic SVG shapes, rendered at 960 by 500 pixels with a yellow circle head, two offset black eye circles, and an arc-based mouth path. Using React for component structure and D3 v7's `arc()` generator to define the mouth’s curved geometry, the code sets the mouth’s inner radius to 0, outer radius to 100, and angles from 0 to π/2. React elements render these shapes into an SVG container, with all positions derived from computed center coordinates and fixed offsets.

This example shows a simple smiley face rendered as an SVG composition of circles and an arc. A yellow background circle with a black stroke forms the head, two black circles serve as eyes, and a d3.arc path creates the mouth. The React components—BackgroundCircle, Eyes, Mouth, and FaceContainer—accept numeric props for position and sizing, while Face assembles them into a centered group. The code uses d3.v7 for the arc generator and React 18 for rendering, with all geometry defined by constants in index.js.

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 the first step toward building a smiley face using React and D3.js, rendering a yellow circle with black eyes, a mouth, nose, and eyebrows as SVG paths. The visualization defines geometric parameters for each facial feature (radii, angles, and offsets) and uses D3's `arc()` API to generate path data for the mouth, nose, and eyebrows. The face is centered in a 960x500 SVG canvas, with the eyes positioned relative to the center using computed offsets. React manages the SVG element tree, while D3's arc generator handles the angular shapes, though the current arc angles for the nose and eyebrows may not accurately represent the intended features.

This example builds a smiley face using React and D3, rendered as an SVG. It shows a yellow circle with a black border, two black eye circles, and a curved mouth created with the d3.arc function. The face is centered on a 960x500 canvas, with all shapes positioned using JavaScript calculations for offsets and radii. React manages the SVG element structure, while D3 provides the arc path generator for the mouth.

Two smiling eyes and an arched mouth complete a yellow circle, producing a simple cartoon face. Built with React components and rendered as SVG, the example composes a background circle, offset eye circles, and a mouth path generated with the d3 `arc` generator. The d3-shape `arc` function creates the mouth’s curved outline, while React’s component structure passes fixed coordinate values for eye offset and mouth dimensions. The face is centered via an SVG group transform, with nested components defining each facial feature.

Smiley Face Part 1

A yellow circle with black outline forms the face, with two black eye circles and a half-arc mouth created using a D3 arc generator. The React component renders these SVG elements, positioning the face at the center of a 960×500 viewport. D3’s `arc()` path generator constructs the mouth with specified inner and outer radii and start/end angles, while the eyes are offset using constant coordinates. The code logs React, ReactDOM, and the arc function to the console, and renders the SVG via `ReactDOM.render` into the root element.
