This example demonstrates the foundational steps of building a visualization with D3 and React. It creates a minimal web page with a bare HTML structure and an empty SVG element appended to the body using D3’s `select` and `append` methods. The JavaScript code contains commented-out exercises on array methods like `push`, `forEach`, `filter`, `map`, `reduce`, and `sort`, illustrating how data transformations work in D3. The visualization itself is purely an empty SVG canvas, with no data or shapes rendered, serving as a starting point for learning JavaScript and D3 syntax.

D3.js

This example uses D3.js v3 within a minimal React-free HTML page to demonstrate the core charting workflow. The code sets up an interactive visualization by selecting an empty body element and appending SVG or canvas elements via D3’s data-join methods. While the provided files contain only the basic scaffolding—a blank `index.html` and an empty `app.js`—the intended purpose is to show how D3 selections and scales build a chart from scratch. The documentation references D3’s force simulation and path generators as potential next steps.

Hello HTML

A minimal SVG canvas is displayed on a blank HTML page, showcasing the foundational setup for a D3.js visualization. The code initializes an SVG element with a width of 960 and height of 500, and uses `d3.select` from the D3 v5 library to reference it. The page imports the D3 library from an external source and includes a separate CSS file for basic styling. This example demonstrates the simplest possible starting point for building a D3 visualization in a React framework.

D3 and SVG

This example demonstrates a minimal D3.js and SVG setup within a React project. The visualization consists of an empty SVG canvas with fixed dimensions, while the accompanying JavaScript logs "111" to the console, showing initial code structure rather than data rendering. It uses D3 v5 and SVG elements, with the HTML page loading the D3 library via CDN. The example serves as a bare-bones starter template for integrating D3 with React, featuring a clean stylesheet and a simple test file.

React D3 Starter

This example presents a minimal React and D3 starter template, displaying an empty SVG canvas within a React application. The code sets up a 960 by 500 pixel SVG element using React’s JSX syntax, rendered into the DOM via `ReactDOM.render`. It imports D3 v7 and React 17 from CDN links, with all styling handled by CSS that removes page margins. The visualization currently shows no data or chart, serving purely as a foundational scaffold for building interactive D3 visualizations within the React framework.

HTML Starter

This example demonstrates a minimal setup for creating a browser-based visualization using D3.js within an HTML page. It renders a simple SVG element that is styled with a red background color using the d3.select API. The page loads D3 version 5 from a CDN and uses a basic script to apply the styling, showcasing the fundamental structure needed to begin building interactive data graphics. The code defines an SVG canvas with fixed dimensions but does not yet include any data-driven marks or transformations.

Introduction to D3

This example demonstrates a minimal introduction to D3, showing how to create an SVG canvas that fills the entire browser window. The code uses the `select` and `append` functions from the D3 library to dynamically add an SVG element to the HTML body, then sets its width and height attributes based on the window’s dimensions. The visualization renders nothing beyond an empty, resizable SVG container, serving as a starting point for more complex D3 projects. The page is built from a barebones `index.html` file with no pre-existing content, relying on JavaScript to construct the visual output at runtime.

HTML Starter

This example demonstrates an empty SVG canvas sized 960 by 500 pixels, providing a minimal starting point for data visualization projects. The code imports D3’s `select` and `arc` functions within a React framework, though the visible rendering relies on a static `<svg>` element. D3 version 5 is loaded via CDN, with JavaScript bundled and executed from a separate `bundle.js` file. The visualization does not display any data or shapes, serving only as a clean template for future D3-based graphics.

HTML Starter

This example demonstrates a minimal HTML page that loads D3 v5 and renders an empty SVG canvas, with JavaScript stubs for data processing and rendering. The code imports D3 via a CDN, selects the SVG element, and sets up dimensions and margins for an upcoming visualization. It references a `parachutes.csv` dataset containing track names, lengths, and types, though the actual rendering and data-binding logic is not yet implemented. The example serves as a bare-bones starting point for building D3 visualizations in a React environment.
