This example renders the full CSS named-color palette as a circular pie chart using React and D3. The visualization displays each color name from a CSV dataset as a slice with its corresponding RGB hex fill, producing a rainbow-like wheel. The code combines React hooks for state management with D3’s `pie` and `arc` generators to compute slice angles and SVG paths. All shapes are drawn as SVG elements within a single group transformed to the chart’s center.

Fork of Fork of Fork of Smiley Face Part II

This example visualizes the named CSS colors as a full-screen pie chart, with each slice representing one color and filled using its corresponding RGB hex value. Built with React and D3 v7, it fetches color data from a CSV file using the `csv` function from D3, then constructs the pie layout with `d3.pie()` and renders the arcs via `d3.arc()` into SVG paths. The chart is centered using a translated `<g>` group, and a loading message appears until the data arrives.

Smiley Face Part One

This example shows a radial visualization of CSS named colors, rendering each color as a pie slice arranged around a central point. The data is fetched as CSV from a GitHub gist and processed using d3.csv and d3.pie. The SVG output is generated through React components, with `BackgroundCircle` and `Eyes` forming a stylized smiley face overlay, while `DataFetchedRadial` maps each color to an arc using d3.arc. A separate tracker component moves a circle in response to mouse events, though it is not rendered in the final view.

A React application renders a horizontal visualization of CSS named colors, where each of the 148 rows displays a color’s hex value as a colored strip. The code loads color data from a CSV file using `d3.csv` and manages state with React’s `useState` and `useEffect` hooks. Each row is a React `<div>` element styled with the color’s background, creating a full-width stacked bar chart. The example demonstrates integrating D3 for data loading with React for declarative SVG and DOM rendering.

Fork of Smiley Face Part II

This example renders a smiley face using React and D3 v7. It loads CSS named colors from a CSV file via `d3.csv` and uses React state with the `useState` hook to manage the data. The visualization displays SVG circles for the face’s features, with the main shape outlined in black. The code demonstrates a React-D3 integration pattern, though the rendering logic is currently incomplete, showing only a loading message until data is fetched.

This example builds an interactive smiley face using React and D3 v5. The page loads a CSS named color dataset from a GitHub gist and displays its file size, row count, and column count in a text overlay. A single circle follows the mouse position across the full window, rendering via SVG elements managed through React state and event handlers. The visualization demonstrates React’s `useState` and `useCallback` hooks for responsive, real-time updates, with D3’s `csv` method fetching and parsing the external data.

Fork of Rendering CSS Colors Data with React & D3

This visualization displays the full set of named CSS colors as a circular pie chart, with each slice filled by its corresponding color. The data loads from a CSV file via `d3.csv`, and React manages the component state with `useState` and `useEffect`. The chart is rendered using React elements for SVG paths, while `d3.pie` computes the arc angles and `d3.arc` generates the path geometries.

Fork of Rendering Data with React & D3

This visualization displays all CSS named colors as a radial burst of pie slices, with each slice filled by its corresponding hex value. It uses React to manage state and render the SVG, while D3 utilities load the CSV data from a GitHub gist and compute the pie chart geometry. The code employs `d3.csv`, `d3.arc`, and `d3.pie` to fetch and transform the data, and React’s `useEffect` and `useState` handle the asynchronous loading and rendering. The colorful result provides a comprehensive, at-a-glance overview of the color palette.

Fork of Rendering data with React.

This visualization displays the 148 named CSS colors as a circular pie chart, with each color represented as a slice of equal angular width. The chart loads color data from a CSV file using D3’s `csv` utility, then renders each slice as an SVG `<path>` element via React. The code uses `d3.pie` to compute arc segments and `d3.arc` to generate the path data, with each slice’s fill color taken from the dataset’s RGB hex values. The React app manages the asynchronous data loading with hooks like `useEffect` and `useState`, and renders the result inside an SVG canvas.
