This pie chart visualizes the distribution of device usage across four categories with varying values. A React component renders an SVG, using d3.pie to compute arc segments and d3.arc to generate the paths. The d3.scaleOrdinal function assigns a distinct color to each device. Text labels are positioned at each slice’s centroid with arc.centroid, displaying the device names directly on the chart. The visualization updates automatically when the container size changes, thanks to a ResizeObserver hook that feeds dimensions into the rendering logic.

Fork of CV: pie chart

This example shows a pie chart visualizing device usage by value across four categories: Smartphone, Tablet, iwatch, and Laptop. The chart is rendered as SVG within a React component using d3.pie and d3.arc to generate the paths and d3.scaleOrdinal for color encoding. Labels are positioned at each slice’s centroid. The visualization uses static data defined inline and d3.v7 APIs to build the chart entirely in App.jsx.

Fork of Pie Chart React & d3

This interactive pie chart visualizes a categorical color palette dataset loaded from a CSV file via `d3.csv`. The React component manages the data with `useState` and `useEffect`, rendering an SVG where each slice corresponds to a row, filled with its `RGB hex value`. The chart uses `d3.pie` and `d3.arc` to compute and draw the pie geometry, with a large outer radius creating a striking radial composition. Data loads asynchronously, displaying a "Loading..." message until ready.

Fork of Fork of React & D3 Starter

This pie chart visualizes monthly expense categories from a CSV file, displaying each category’s proportional share with a legend and value labels. Built with React and D3 v7, it uses `d3.pie` to compute arc segments and `d3.arc` to generate SVG paths, rendered with a categorical color scheme from `d3.scaleOrdinal`. The chart draws arcs and text labels onto an SVG canvas, with a legend constructed iteratively from the data.

Fork of Visualize data in React & D3 - use Pie chart

This example shows a pie chart of CSS named colors, where each slice represents one color and is filled with its corresponding RGB hex value. The chart is built by combining React for component structure and state management with D3 utilities for data loading and geometry. It uses `d3.csv` to fetch the color data from a GitHub gist, `d3.pie` to compute slice angles, and `d3.arc` to generate SVG path commands. The visualization renders as an SVG, centered on a full-screen canvas, with each slice equally sized because `pie().value(1)` assigns a constant weight.

Fork of Rendering data using react and D3

A colorful pie chart displays CSS named colors as equal-sized slices, with each slice filled using its corresponding RGB hex value from a CSV dataset. The visualization uses React hooks like `useState` and `useEffect` to fetch and manage the data, while D3’s `pie()` and `arc()` functions compute the angular and radial geometry for the SVG paths. The chart is rendered as an SVG element with a centered group transformation, and the color mapping directly applies each data entry’s RGB value to its slice fill.

Fork of Rendering data with React

A pie chart displays CSS named colors as individual slices, with each slice filled using the color’s hex value from a CSV dataset loaded via `d3.csv`. The React component uses `useState` and `useEffect` to fetch and store the data, while `d3.pie` and `d3.arc` compute the arc paths rendered as SVG `<path>` elements. A loading fallback shows text until the data arrives, and the chart is centered within a fixed 960 by 500 viewport.

Fork - Colors pie view with D3 and React

A circular pie chart displays color swatches in a color wheel, with each slice filled by a color from a CSV dataset loaded from a GitHub gist. This D3.js and React example uses `d3.arc` to generate the pie slice paths and `d3.pie` to compute angular values, though the code manually calculates start and end angles. The chart is rendered as an SVG, centered within a fixed 960 by 400 viewport. Individual color values from the CSV's "HEX" column directly determine the fill of each path, creating a rainbow-like ring of distinct hues.

Fork of Fork of loading data w/ react and d3

A pie chart displays the proportional distribution of named colors, using their RGB hex values for the fill color of each slice. The chart is built with React, which manages the asynchronous loading of a CSV file via `d3.csv` and conditional rendering, while ReactDOM mounts the component. The geometric layout and slice drawing rely on the D3 modules `d3.arc` and `d3.pie`, which compute the arc paths for each data row. The example demonstrates a minimal integration of D3’s data-processing and shape-generation functions within a React component structure, rendered as an SVG graphic.
