D3 Tutorial

D3.js intro!!

This example creates a cheerful smiley face entirely with SVG shapes inside a React application. The visualization uses D3 version 6 to append a large yellow circle for the face, two smaller black circles for asymmetrical eyes, and a curved path for the mouth. The mouth is generated using D3’s `arc()` function, which constructs an annular sector path. The code explicitly sets SVG attributes like `fill`, `stroke`, and `transform` to position and style each geometric element on a 960 by 500 canvas.

D3.js Starter

This example renders a smiley face in an SVG canvas using D3.js version 5. It draws a yellow circle for the head, two black circles for the eyes, and a semi-circular path for the mouth, all positioned via width and height attributes retrieved from the SVG element. The code uses d3.select to append shapes and d3.arc to generate the mouth path, with styles defined in an external CSS file. It demonstrates basic SVG manipulation and shape generation within a React framework using D3’s selection and arc APIs.

Hello HTML

This example renders a classic smiley face as a static SVG graphic using React and D3.js. The code defines a yellow circle with a black stroke, two smaller circles for eyes, and a mouth drawn with the `d3.arc` function to create a partial ring path. The React app returns an SVG element whose dimensions and geometric properties are set through JavaScript variables, and the scene is centered using a coordinate transformation.

This example creates a static smiley face using SVG shapes, rendered through a plain React component in the bundled visualization. The code draws three circles directly in the SVG markup: a large yellow circle for the face, two smaller black circles for the eyes, and a yellow nose with a black stroke. The rendering uses inline SVG elements without D3.js functions or data-driven joins, relying solely on hardcoded coordinates and styling attributes. The page, defined in index.html, loads JavaScript to display the composition on a 900x400 canvas.

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.

D3.js Starter

This example shows a simple smiley face rendered as SVG elements, including a yellow circle for the face, black circles for eyes, and a path for the mouth. The code uses d3-selection’s `select` and `append` methods to build the SVG structure, and d3-shape’s `arc` function to generate the mouth’s curved path. The visualization is static, with dimensions pulled from the SVG’s width and height attributes. It serves as a minimal starter template for integrating D3 with React and SVG rendering.

D3_React Smiley Hello HTML

This example renders a simple yellow smiley face as an SVG graphic, composed of a circle for the head, two smaller circles for eyes, and a D3 arc path for the mouth. It is built with React 18 and D3 v7, using JSX to define the SVG elements and the `arc` generator from D3 to compute the mouth’s path. All coordinates are calculated relative to the center of a 960 by 500 viewport, and the graphic is rendered into the DOM via `ReactDOM.render`.

D3

A yellow smiley face is drawn on a red SVG canvas using D3.js v6, centered within a 500x500 viewport. The face includes two eyes, brief animated eyebrow movements via `transition().duration()`, and a mouth created with `d3.arc()`. The example demonstrates basic SVG shape creation, attribute manipulation, and animation in a React environment.
