Forked from D3 Starter

This example demonstrates how to render three black rectangles in an SVG canvas using a React component with D3 version 7. The code uses the `select` function from D3 to bind an array of three data objects to appended rectangular elements, positioning them diagonally via `attr("x")` and `attr("y")`. It shows a basic data join pattern where the enter selection creates rectangles, highlighting the integration of React refs (via `useRef`) with D3’s imperative DOM manipulation inside a `useEffect` hook.

This example demonstrates basic SVG graphics drawn with D3.js, including two circles and three rectangles whose heights correspond to data values from a JavaScript array. The code uses D3's `select` API to target the SVG element and append shapes, while also utilizing vanilla JavaScript `querySelectorAll` to add click handlers. The visualization serves as a minimal starter template, combining static data-driven bar-like shapes with interactive alert functionality.

This example demonstrates basic SVG shapes created with D3.js and vanilla JavaScript, rendering two circles and three rectangles of varying heights on a blank canvas. The code uses D3’s `select` to append the shapes to an SVG element, with an array `myData` supplying rectangle heights. It also queries all `rect` elements via `document.querySelectorAll` and attaches a click handler that logs a message to the console. The page is styled with CSS, including a large centered greeting and red circles.

Fork of D3 Starter

This example demonstrates a minimal D3 starter template that renders a collection of rectangles in an SVG. The code uses D3’s `select` and `selectAll` with the data-join pattern to bind an array of generated objects (each with height and width properties) to SVG `rect` elements, positioning them at the origin. It relies on D3 v7, loaded via a CDN, and a `bundle.js` file, while the page also includes an embedded YouTube tutorial. No scales, axes, or interactions are present; it simply shows foundational data-binding and element creation.

This example demonstrates basic SVG shapes and data binding using D3.js. It appends two circles and three rectangles to an SVG container, with the rectangle heights determined by values from a hardcoded array. The code uses `d3.select` to access the SVG element and `append` functions to create visual elements. Interactive behavior is added by attaching `onclick` handlers to the rectangles via the browser's `querySelectorAll` and `setAttribute` methods.

Fork of React & D3 Starter

This example demonstrates a minimal integration of React and D3, showing a single div element rendered with the text “Hello D3 & React” through React’s `createRoot` and `useRef` hooks. The code uses `select` from D3 v3 to update the DOM node’s content after React mounts. It also applies D3’s selection and style methods to a static set of four divs, setting their widths and alternating background colors based on index, and binds an array of data values via `.data()` to demonstrate basic data joining. The example serves as a starting point for combining React’s component model with D3’s imperative selection and manipulation APIs.

This example shows a basic HTML page that uses D3.js to draw three circles and three rectangles in an SVG container. The rectangles are positioned using hardcoded data from a small array, while the circles have fixed coordinates. The code demonstrates direct SVG manipulation through both D3 selections and native DOM methods, logging elements to the console and adding onclick handlers to each rectangle. The page includes simple CSS styling for the message text and circle appearance.

Fork of D3 Starter

A simple D3 starter demonstrates the basics of rendering static SVG elements alongside a React app. The page displays a single yellow circle with a black stroke, drawn using an inline SVG element, while a React component renders the text "Hello" into a separate div. The code loads React and ReactDOM from CDN, uses JSX to define the component, and renders it with `ReactDom.render`. No D3 functions or dynamic data are involved; the example focuses on establishing the project structure.

This example demonstrates a basic SVG visualization using D3.js, drawing two circles and two rectangles on a canvas. The circles are positioned at different coordinates with a fixed radius, while the rectangles are placed at the same x and y positions but vary in height, with one using a value from the `myData` array. The code imports `select` from D3 to append elements, and additionally uses native `querySelectorAll` to log the rectangle elements to the console. Styling is applied via CSS, with red circles and minimal body margins.
