This example shows a smiling face built from a yellow circle, two eyes, and an arc-based mouth, centered in an SVG canvas. It demonstrates how to combine React components with D3 shape generators, using `d3.arc` to create the mouth path and passing props like `eyeOffsetX` and `eyeR` to reusable components. The rendering relies on React’s declarative JSX structure, with D3 v5 and React 16 loaded via CDN, and the face is positioned using an SVG `<g>` transform.

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 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 using React and SVG, composed of a yellow background circle, two eyes, and a mouth. The drawing is built from separate React components, each returning SVG elements, and is assembled inside a single `<svg>` tag. The mouth shape is generated programmatically using the D3 `arc` function, which defines an annular sector with specified inner and outer radii and angle ranges. The face is centered using an SVG group transform, and all elements are positioned relative to the center point.

Hello HTML

This example shows a simple smiling face composed of SVG shapes, built with React components and D3. The face includes a yellow circular background, two black eyes, and a mouth drawn using D3's arc generator. The code demonstrates reusable React components for each facial feature and a container component that manages the SVG coordinate system. The face is rendered using SVG within React, with D3 v7 used specifically for the mouth's arc path.

Hello HTML

This example shows a cheerful, cartoon-like face composed of a yellow circle with a black outline, two black eyes, and a curved mouth. Built with React, it renders the face as an SVG using the `d3.arc` API to generate the mouth’s path. The `Face` component combines a `BackgroundCircle`, `Eyes`, and `Mouth` inside a translated group, with all geometry defined by parameters like `offsetX` and `mouthRadius`. The visualization is a minimal, static composition, demonstrating how React components can encapsulate and arrange D3-generated shapes.

Hello HTML

This example shows a smiling face rendered as an SVG in a React component, featuring two eyes and a complete circular mouth created with D3’s `arc()` generator. The code uses ReactDOM to mount the component into the page, while D3 v5 provides the arc path for the smile. The face is drawn with hard-coded coordinates, including a yellow circle with a black stroke, positioned eyes, and a mouth path, all inside a static SVG with fixed dimensions.

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.
