Smiley Face Part 1

A smiling face is drawn on a yellow circular head with a black outline, two solid black eyes, and an open mouth formed by a thick arc. The visualization uses React to render the SVG and D3's `arc()` function to generate the mouth path. The head, eyes, and mouth are positioned relative to the center of a 960x500 coordinate space, with the face built from basic SVG shapes. The example demonstrates combining React's DOM rendering with D3's geometry utilities to create a simple yet effective data-driven graphic.

Smiley Face Part 1

A smiley face is rendered as a yellow circle with two black eyes and an arched mouth, all drawn relative to a central point. The React app uses SVG elements for the face, while D3's `arc` generator creates the mouth path with specified inner and outer radii and start/end angles. The background circle, eyes, and mouth are positioned using computed offsets from the center, with the eye and mouth radii defined as constants. The code imports `arc` from `d3` and uses React's `ReactDOM.render` to mount the component.

Smiley Face Part 1

This visualization draws a cheerful smiley face using React components for the SVG elements. The face consists of a yellow background circle, two elliptical eyes, red cheeks, and an arc-based mouth. D3’s `arc()` generator creates the mouth path, while React’s component structure with props manages coordinates and dimensions. The rendering uses SVG within a React app, with all facial features positioned relative to a central translation point.

This example shows a simple smiley face drawn with React and D3’s `arc` generator for the mouth. A yellow circle with a black stroke forms the head, while two solid black circles serve as eyes. The mouth is a full circular arc with inner and outer radii, rendered as an SVG path. The SVG canvas is fixed at 960 by 500 pixels, with all elements positioned relative to the center using a `translate` transform. React renders the component hierarchy, and D3’s `arc` API computes the path data.

Smiley Face Part I

A smiley face is drawn using React and D3 v7, rendered as SVG shapes. The face consists of a yellow background circle, two black eyes, and a curved mouth created with the `d3.arc()` generator. React components structure the code, with separate modules for the background, eyes, and mouth. The mouth’s arc geometry is defined by computed radius and angle values, while the entire group is centered using an SVG transform.

Smiley Face - Part 1

A smiley face is drawn using React and D3, with a yellow circular head, two black eyes, and a partial mouth arc. The SVG rendering uses D3’s `arc` generator to create the mouth path, while positions and sizes are defined by constants for offsets and radii. The face is centered in a 960×500 viewport, with the head radius calculated from the height minus stroke width.

Smiley Face Part I

A yellow circle with a black stroke forms the head of a smiley face, with two black eyes offset symmetrically above the center. The mouth is drawn as a semicircular arc using `d3.arc()` with inner and outer radii, creating a thick path spanning from 90 to 270 degrees. The visualization is built with React (v17) rendering inline SVG, and uses D3 v6's `arc` API to compute the mouth path. The code defines all dimensions as constants, with the face radius derived from the viewport height.

A yellow smiley face rendered with React and SVG uses D3.js arc segments to draw a mouth. The face consists of concentric circles for the head and eyes, with blue elliptical pupils, all positioned using SVG transforms. The code defines geometric parameters like eye offsets and radii, then computes the mouth path using D3's arc generator with specified angles. The visualization demonstrates combining React's declarative UI structure with D3's geometric path generation.
