Smiley Face Part 1

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.

This example renders a smiley face using React and D3.js version 6, drawing SVG shapes onto a 960-by-500 canvas. The face consists of a yellow circle with a black stroke for the head, two dark circles for eyes, and a mouth created with D3’s `arc` helper, which defines an annular sector path with specified inner radius, outer radius, and angle range. The React component computes layout constants such as center coordinates, eye offsets, and mouth dimensions, then applies a transform to center the group. The rendering uses static SVG elements without interaction or animation.

Smiley Face Part 1

This example renders a classic smiley face using React and D3, drawing a yellow circle with black outline, two eyes, and an arc-shaped mouth on an SVG canvas. The face is centered using a translated group element, with fixed pixel offsets for the eyes and D3’s `arc()` generator defining the mouth’s inner and outer radii and angles. Hard-coded dimensions and stroke widths position every shape, demonstrating a static, declarative composition without data input. The code uses React’s JSX syntax and the `arc` API from D3 v5.

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 1

This example shows a smiley face constructed from basic SVG shapes in a React component. It renders a yellow circle with a black stroke for the face, two black circles for eyes, and a curved mouth generated with the `arc` function from D3. The `transform` attribute positions the face group at the center of the 960 by 500 pixel SVG canvas. React manages the component structure, while D3 version 6 handles the arc path calculation using specified inner and outer radii and start and end angles.

Smiley Face Part 1

This example uses React with D3 v7 to construct a classic smiley face from SVG shapes. It renders a yellow circle with a black stroke as the background, two smaller circles for eyes, and a mouth drawn using D3's `arc` generator with specified start and end angles. All elements are positioned relative to a central transform group, demonstrating how React components can encapsulate D3 shape functions for declarative visualization.

Smiley Face Part 1

This example displays a yellow smiley face centered on an SVG canvas, built entirely with React and D3 v6. The face consists of a circular head, two black eye circles, and a curved mouth created using the `arc` generator from the D3 shape module. The `arc` function constructs the mouth path with specified inner and outer radii and angular extents, while React renders the SVG elements declaratively. The code defines all dimensions as constants, including eye offsets, radius, and stroke width, layering the shapes within a translated group element.

Smiley Face Part I

This example renders a yellow smiley face in SVG using React and D3 v7. It shows a circular face with two eyes and a semicircular mouth, all positioned relative to a central coordinate system via a group transformation. The code uses `d3.arc` to generate the mouth path, with explicit `innerRadius` and `outerRadius` values, while the face and eyes are simple SVG `circle` elements. Stroke width and radius calculations adjust the face size based on the fixed 960×500 viewport.
