Fork of Rendering (barchart)(Axis : the margin convention) data with react and d3

This example shows a horizontal bar chart of the top ten countries by 2020 population, loaded from a CSV file using d3.csv and rendered as SVG elements. React manages the data state and maps each row to a styled rectangle, with d3-scale’s scaleBand and scaleLinear computing the bar positions and widths. The chart applies a simple margin convention using a translated group element, and d3.v5 utilities fetch and parse the numeric population values before React re-renders the visualization.

Rendering (barchart) data with react and d3

A bar chart displays United Nations population estimates for 2020 across ten countries, using horizontal bars scaled by population size. The visualization loads CSV data via `d3.csv` and manages the asynchronous result with React’s `useState` and `useEffect` hooks. React renders SVG rectangles, while `d3.scaleBand` and `d3.scaleLinear` compute bar positions and widths. The data pipeline converts the population string to a number and filters to the top ten entries before rendering.

Rendering (pie) data with react and d3

A pie chart built with React and D3 displays the distribution of CSS named colors by their RGB values. The visualization loads color data from a remote CSV file using D3's `csv` utility and renders each color as an SVG path arc via `d3.arc` and `d3.pie`. React's `useState` and `useEffect` manage the asynchronous data fetch and state, with a loading message shown before the chart appears. The example demonstrates integration of React components with D3's geometry APIs for declarative SVG rendering.

Vega-Lite API Template

This example visualizes the Auto MPG dataset from the UCI Machine Learning Repository as a scatter plot, mapping miles per gallon, horsepower, origin, weight, and car name to the x-axis, y-axis, color, size, and tooltip channels. It uses the Vega-Lite API to construct the specification programmatically, with Vega and Vega-Lite for rendering and Vega-Tooltip for interactive hover details. Data is loaded via d3.csv, and the chart fills the browser window with a custom configuration for font sizes and axis styling.

Loading data with react and d3

This example demonstrates how React and D3 work together to load and summarize a CSV dataset of CSS named colors. The visualization displays a text summary showing the file size, number of columns, and row count once the data has been fetched. It uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, while `d3.csv` retrieves and parses the remote data. The `d3.csvFormat` API calculates the formatted data size, and ReactDOM renders the final message.

Mouse Follower

The example shows a black circle that follows the mouse cursor across a blank SVG canvas, updating its position in real time as the pointer moves. The code uses React hooks, specifically `useState` and `useCallback`, to track the mouse coordinates and re-render the circle’s `cx` and `cy` attributes on every move event. It renders a 960×500 SVG element with a single circle of radius 30, and the mouse position is captured via the `onMouseMove` handler.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL, displaying a summary of the dataset’s size in kilobytes, number of columns, and number of rows. It uses the D3.js v5 library, specifically the `d3.csv()` function for fetching and parsing, and `d3.csvFormat()` to measure the data size. The parsed data comes from a CSS Named Colors dataset hosted as a gist. The result is rendered as plain text inside an HTML `<pre>` element.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data in a React application using D3 v5. It fetches a CSV file containing CSS named colors from a GitHub gist, then logs the raw text content to the browser console. The code uses the Fetch API with async/await syntax, wrapping the process in a custom `fetchText` function, and relies on D3’s bundled utilities for handling the data. The visualization itself is minimal, focusing on the data-loading pipeline rather than displaying the parsed results visually.

Fork of Hello HTML

This fork of Hello HTML renders a simple, cheerful face as a React component in an SVG. The face is built from a yellow background circle, two black eyes, and a mouth formed by a d3 arc path. The code uses React components to structure the face’s parts, with the mouth’s shape defined by the d3 `arc` generator’s inner and outer radii and start and end angles. The SVG output is centered within a 960 by 500 viewport.
