Smily Face Part 1

Smily Face Part I

This example builds the upper half of a smiley face using React components and D3.js. It shows a yellow background circle, two black eyes, and a partial mouth arc, all rendered as SVG elements within a coordinate system centered on the canvas. The mouth shape is generated with D3’s `arc()` generator, which produces a path based on inner and outer radii and angular start and end points. The face’s geometry is parameterized through component props, allowing for flexible control over eye offset, radii, and stroke width.

Smiley Face Part 1

This example renders a basic smiley face using React and D3 v7, drawing SVG shapes on a 960×500 canvas. It shows a yellow circle with a black stroke for the head, two black eye circles positioned symmetrically, and a smile created with the `arc` generator from D3. The arc uses inner and outer radii with start and end angles to form a mouth shape. All geometry is computed from center coordinates, radius, and offset variables, then transformed into place using an SVG group element.

Smiley Face Part 1

A half-finished smiley face rendered in SVG with React and D3. The code draws a yellow circle head with a black stroke, two black eyes positioned symmetrically, and a mouth arc created using the `d3.arc()` generator. The arc uses specified inner and outer radii with angles from 90 to 270 degrees, leaving the smile incomplete. All coordinates and dimensions are calculated relative to the SVG width and height, with transformations translating the center to the middle of the canvas.

Smiley Face Part I

This example renders a smiley face using React and D3 v7, drawing yellow circles for the head, black circles for the eyes, and a D3 arc path for the mouth. The SVG is centered via a transform, with all shape geometry defined by scalar variables for offsets, radii, and stroke width. The visualization demonstrates declarative composition of SVG primitives within React’s render tree, using D3’s `arc` generator to compute the mouth’s curved path based on start and end angles.

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.

Smiley Face Part I

A smiling face constructed from basic SVG shapes sits at the center of a yellow circle with a black stroke. Two black eye circles and a curved mouth path, drawn using D3's `arc()` generator, complete the half-finished expression. The React component renders these shapes inside an SVG container, with D3 v7 handling the arc's angles and radii. The fixed dimensions and coordinate translations position the face precisely on a 960-by-500 canvas.

Smiley Face Part 1

A yellow smiley face with black outlined eyes and a curved mouth is rendered as an SVG inside a React component. The code uses d3.arc to generate the mouth path, while the circle elements for the face and eyes are created directly with JSX. The face and features are positioned relative to a central transform using width and height constants, with a stroke width of 10 pixels applied to the background circle. The example demonstrates combining React’s declarative rendering with D3’s geometry utilities for SVG shapes.

Smiley Face Part I

A smiley face rendered with React and D3 in an SVG, centered on a 960x500 canvas. Yellow circles form the head and black eyes, while a mouth is drawn using the D3 `arc()` generator with a semicircular path. The layout relies on fixed pixel offsets for features, computed from the center and radius values. The example demonstrates declarative React components combined with D3's shape APIs for precise geometric control.
