A smiling face is drawn with SVG shapes, including a yellow circle, red eyes, and a curved mouth, using React components for each part. The face is composed from a `BigCircle`, two `Eye` components, and a `Mouth` component, all positioned via transforms and props. The `Mouth` uses D3's `arc` to generate the path, while the app loads data asynchronously from a CSV URL via `d3.csv`, displaying the row and column count. The visualization is rendered with React and D3 v7, with SVG output.

Hello HTML

A smiling face rendered as a yellow SVG circle with black stroke, two eyes, and an arc-shaped mouth, built with React components and D3's `arc` generator. The code defines the face's dimensions and positions using constants, then draws the mouth path via `mouthArc()` with specified inner and outer radii and start/end angles. The SVG output is created through React's `ReactDOM.render` into a root element, while D3 is loaded via a script tag alongside React production builds.

Hello HTML

This example renders a smiling face composed of SVG shapes, including a yellow background circle, two eyes, and a mouth created with a D3 arc path. The face is built from reusable React components—BackgroundCircle, Eyes, Mouth, and FaceContainer—that accept props for positioning and sizing. The FaceContainer establishes an SVG coordinate system centered at a specified point, while D3’s `arc` generator defines the mouth’s curved shape. The visualization demonstrates how React and D3 can be combined to create declarative, parameterized graphics.

Hello HTML

A yellow smiley face rendered in SVG shows how React and D3 can be combined to draw simple shapes. The face uses two circles for eyes and a D3 `arc()` generator for the mouth, with all elements positioned relative to a central transform. React manages the SVG markup, while D3 provides the path calculation for the mouth arc. The example demonstrates a minimal setup using React 17, ReactDOM, and D3 v7, with static data encoded directly in the component.

Hello HTML

A smiling face rendered as a yellow circle with black stroke, two eyes, and a halfway smile (an arc from 180° to 270°). The face is drawn with React components using SVG, with each facial feature (background, eyes, mouth) as a separate reusable component. It uses d3.arc to generate the mouth’s path, and d3 is loaded alongside React 17 and D3 v7. The face’s dimensions and proportions are passed as props from index.js.

Hello HTML

This example displays a cheerful, cartoon-like face constructed entirely from SVG shapes, centered on a yellow circle. Built with React and D3 v7, the visualization demonstrates how D3’s `arc` API generates a curved mouth path within a declarative component structure. The face’s features, including its eyes and smile, are positioned via computed coordinates passed to reusable `Eyes` and `Mouth` components inside a container that translates the drawing to the canvas center.

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

A yellow smiley face rendered with React and D3 draws on an SVG canvas. The face uses a yellow circle with a black stroke for the head, two black circles for eyes, and a D3-generated arc path for the mouth. The React component structure defines the SVG elements, while the D3 `arc()` generator calculates the mouth’s curved shape. The example demonstrates a minimal integration of React for UI composition and D3 for geometric path generation, with all drawing occurring in the SVG coordinate space.

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.
