Fork of Refactored Bar Chart

This example displays the top 10 most populous countries from the United Nations World Population Prospects 2019 dataset as a horizontal bar chart with axes. The React app uses `d3.csv` to load data, `scaleBand` and `scaleLinear` to position bars, and renders SVG via React components for axes and marks. Population values are parsed as numbers and sorted by their 2020 figures.

Fork of Pathetic Bar Chart

This example displays the ten most populous countries as horizontally oriented bars without axes or labels, using a simple SVG bar chart. It loads United Nations World Population Prospects 2019 data via `d3.csv`, then sorts the first ten rows by population. React state management with `useState` and `useEffect` handles the asynchronous data loading, while D3’s `scaleBand` and `scaleLinear` map countries and population values to screen coordinates. The bars are rendered as SVG `<rect>` elements, with each bar’s width proportional to its country’s 2020 population estimate.

Fork of The Margin Convention Outtake

This visualization displays the top 10 most populous countries as a minimal bar chart, with no axes or labels, leaving the bars to float in an empty SVG canvas. The chart uses React for rendering and D3 v5’s `scaleBand` and `scaleLinear` for positioning and scaling, with data sourced from the United Nations World Population Prospects 2019 via a CSV. A large right margin compresses the bars into the left portion of the view, emphasizing the absence of a conventional chart frame.

Fork of Fork of Fork of Loading Data with React & D3

This example visualizes CSS named colors as a circular pie chart, with each colored slice representing a single color from a dataset loaded via D3. It shows the distribution of color names across the spectrum, using the RGB hex value for each slice’s fill. The code loads the CSV data with `d3.csv` into React state via `useState` and `useEffect`, then renders SVG paths generated by `d3.arc` with calculated start and end angles. React handles the component lifecycle, displaying a loading message until data arrives.

Fork of Fork of Loading Data with React & D3

This example visualizes CSS named colors as horizontal bars, with each bar’s background color set to the color’s RGB hex value from the dataset. It uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, and D3’s `csv` utility to fetch the color data from a GitHub gist URL. While the data is loading, the display shows the text “Loading...” in large font. Once loaded, the bars render in a vertical stack, demonstrating how React state updates trigger re-renders with D3-loaded data.

Fork of Loading Data with React & D3

This example displays summary statistics about CSS named colors, loading the data from a CSV file hosted on GitHub. It shows the file size in kilobytes, the number of rows, and the number of columns as text in a large monospace font. The app uses React hooks (`useState`, `useEffect`) to manage asynchronous data loading, while D3’s `csv` function fetches and parses the dataset. A custom `message` function formats the statistics, and React renders the result or a “Loading…” placeholder.

Fork of Loading and Parsing CSV Data

This example displays a large-format text summary of a CSV dataset, specifically the CSS Named Colors collection, showing its size in kilobytes, row count, and column count. The visualization uses D3.js version 5 to load and parse the remote CSV file via `d3.csv`, then formats the statistics using `d3.csvFormat`. The resulting message is rendered inside an HTML `<pre>` element, with the code demonstrating both the primary `d3.csv` approach and alternative commented methods using `fetch`, async/await, and `d3.csvParse`.

Fork of HTML Starter

This example displays a summary of a CSV file containing CSS named colors. It fetches the data from a remote gist URL, then computes and presents the file size in kilobytes, the row count, and the column count within an HTML `<pre>` element. The code uses the D3.js version 6 library, specifically the `d3.csv` and `d3.csvFormat` functions, to handle data loading and formatting. The visualization is a simple text-based report of the dataset's structure, rendered on a plain HTML page.

Fork of Fork of Fork of Smiley Face Part II

This example displays a single yellow circle that moves with the mouse over a fixed SVG canvas. The circle’s center coordinates are tracked by React state, updated via an `onMouseMove` event handler on the SVG element. Using React’s `useState` and `useCallback` hooks, each mouse movement re-renders the circle to the new position. The SVG is generated through ReactDOM rendering, with a reactive drawing that directly mirrors pointer location.

Fork of Fork of Smiley Face Part II

A React application renders a smiley face as a single SVG circle that follows the mouse cursor across a 960×500 viewport. The circle’s position updates via React’s `useState` and `useCallback` hooks, triggered by the SVG’s `onMouseMove` event, which captures `clientX` and `clientY` coordinates. Using ReactDOM to mount the app, the visualization demonstrates interactive state management within a minimal HTML page, with no external data sources or animation libraries.

Fork of Fork of Smiley Face Part II

A cartoon smiley face composed of stylized SVG eyes and a large grin is rendered on a yellow circular background. The visualization uses React components, with the `Eyes` and `Smile` components defining complex vector paths and shapes, and the main `App` component composing them with transforms. The face is built entirely from static, pre-defined SVG elements, with the overall layout and scaling handled through inline `transform` attributes.

Fork of Smiley Face Part II

A cartoon smiley face rendered with SVG paths and shapes combines a large yellow circle with stylized, non-geometric eyes and a wide, expressive mouth. Built with React and ReactDOM, the code structures composable `Eyes` and `Smile` components that are transformed and scaled within an SVG canvas. SVG ellipses and paths, colored via CSS classes, create the detailed facial features, with the overall composition assembled in a single React app instance.

HTML Starter

This example shows a simple yellow face composed of SVG circles and an arc-shaped mouth, centered within a 960×500 viewport. The code uses React to render the SVG elements, with D3’s `arc` generator defining the mouth’s path. Styling is handled via CSS, and the face’s geometry is computed from fixed constants like `faceRadius` and `eyeOffsetX`.

Fork of Let's make a face with D3.js!

A smiley face built with SVG and animated with D3.js demonstrates fundamental DOM manipulation. Yellow circular head, two eyes, rectangular eyebrows, and a curved mouth are created using D3 selections and the `d3.arc` path generator. The eyebrows repeatedly move up and down via chained `transition` calls, each lasting two seconds. The code uses D3 v5, imports `select` and `arc` from the library, and renders entirely in SVG without external data.
