This example uses React and D3 v7 to render an SVG smiley face, built entirely from primitive geometric shapes. The violet background circle, eyes, and mouth are positioned relative to the center of the viewport. The smile is generated using D3’s `arc()` function with defined inner and outer radii and start and end angles, while the eyes are simple circles with offsets. The code demonstrates a hybrid approach, combining React’s declarative component structure for the SVG elements with D3’s utility functions for arc path generation.

Hello HTML

This example renders a simple smiley face in SVG using React and D3. The face is composed of a yellow background circle, two black eye circles, and a mouth path generated with the `arc()` function from D3. The code uses React to create the SVG elements and computes coordinates with static variables, such as `eyeOffsetX` and `eyeOffsetY`. The mouth arc is drawn with an inner and outer radius, starting and ending angles defining a half-circle shape. The visualization shows basic composition and DOM manipulation with React 17 and D3 v7.

Hello HTML

This example renders a simple smiley face using React and D3.js, drawing SVG shapes on a yellow circular background with black stroke. The face features two eyes and a mouth created with the `arc()` generator from D3, positioned via a group transform. React manages the component structure and rendering into the DOM, while D3’s arc API defines the mouth’s inner and outer radii and angles. The result is a minimal, interactive-free visualization demonstrating how to combine React’s declarative UI with D3’s geometric utilities for static SVG output.

Hello HTML

This example shows a smiley face constructed from SVG primitives, with a yellow circular head, two dark eyes, and a curved mouth. The visualization is built using React 18 for component rendering and D3 7’s `arc` generator to define the mouth’s path geometry. The drawing is centered via a `translate` transform, and all shapes—circles and a path—are rendered as SVG elements within a fixed 960×500 canvas. The code demonstrates a simple, composable approach to combining React’s declarative structure with D3’s geometry utilities.

Hello HTML

This example displays a classic smiley face rendered as an SVG graphic within a React application, using D3 for one shape. A yellow circle forms the head, with two black circles for eyes and a D3 arc path creating the mouth, all positioned via SVG transforms. The code leverages `d3.arc()` for the mouth geometry, while React manages the component structure and renders the SVG elements directly, combining both libraries in a single visualization.

Hello HTML

This example renders a stylized smiley face using React and SVG, with D3’s `arc()` helper generating the mouth path. The face is centered via a translated `<g>` group, and features yellow circular head, white eyes with black pupils, eyebrows, and a nose line, all drawn as primitive SVG elements. React manages the component structure, while D3 v5 provides the arc geometry. The code defines fixed constants for dimensions and offsets, demonstrating a minimal integration of React with D3 for static, declarative SVG visualization.

Hello HTML

This example renders a smiley face using React and D3’s `arc` function. The SVG contains a yellow circle for the face, two black eyes positioned via offset constants, and a mouth drawn as an arc path with `d3.arc()`. The code defines a React component that returns SVG elements, with sizes and coordinates computed from fixed width and height values. It demonstrates combining React’s declarative JSX with D3’s geometry utilities inside an SVG rendering, using d3.v6 and React 17.

Hello HTML

This example displays a simple smiley face constructed from SVG primitives, with a yellow circular head, black outline, two eyes, and an arc-shaped mouth. The visualization uses a React component to define the SVG structure, while D3’s `arc` API generates the mouth path geometry. Rendering relies on ReactDOM to mount the component into the HTML page, with D3 v7 loaded via CDN. The code demonstrates the integration of React’s declarative syntax with D3’s geometric utilities, using explicit pixel coordinates for layout.

Hello HTML

This example renders a smiley face using React components to create SVG elements. The code uses ReactDOM to mount an App component that draws circles for the face, eyes, and an arc for the mouth via d3.arc(). It demonstrates React’s declarative syntax for SVG with JavaScript expressions for dynamic values like coordinates and stroke widths, while the commented HTML shows an equivalent static SVG version. The visualization uses d3.v7 and React 17 to produce a simple, interactive-free graphic.
