Smily Face Part I

Smiley Face Part 1

This example draws a yellow smiley face in an SVG using React and D3. The face consists of a large circle for the head, two smaller circles for eyes, and a D3 arc path for the mouth. The layout is centered on a 960 by 500 canvas, with fixed pixel offsets for the eyes and a mouth arc that covers the lower half. The code uses ReactDOM to render the SVG, and the D3 `arc` API with inner and outer radii to generate the mouth’s path.

Smiley Face Part I

This example renders a smiley face using React and D3 version 5. The face is composed of SVG circles for the yellow head, eyes, and red nose, with a black stroke outline. A mouth is drawn using the `d3.arc` generator with configured inner and outer radii and angular extents. All shapes are positioned relative to a central point using a group transform, and the layout adapts to fixed width and height dimensions.

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.

Smiley face part 1

This example renders a classic yellow smiley face using D3 v7 and React. It constructs the face from SVG shapes, with a large yellow circle for the head, white eye regions with brown pupils, and D3 arc paths for the mouth and nose. The `d3.arc` API defines the mouth and eye-lash arcs using inner and outer radii with start and end angles. The composition is centered on a 960 by 500 canvas, and the code explicitly uses React's `ReactDOM.render` to mount the component.

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.

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 I

This example uses React and D3 to render a simple SVG smiley face. The React component computes coordinates for a yellow circle face, two black eyes, and a mouth using constant variables for width, height, and offsets. The SVG output is drawn with a yellow fill, black stroke, and a fixed stroke width. The code uses the ReactDOM `render` method to mount the component into the HTML root element, with D3 loaded but not directly used in the visible logic.

Smiley face part 1

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.
