Donut Example Re-imagined and Broken

Donut Example Re-imagined

A donut chart rendered with React and D3 v5 uses the `d3.arc` and `d3.pie` APIs to display five slices in a ring. A mouth-shaped arc sits at the center using a separate `mouthArc` path. A button labeled "Transform" regenerates random data through `generateData`, updating the chart via React state and D3 selection joins. The component also includes commented-out code for displaying formatted values using `d3.format`.

Donut Example Re-imagined 2 Final Week

This example shows an interactive pie chart built with React and D3 v5 that visualizes firearm, suicide, and alcohol-related death data from a CSV file. The chart displays a semi-circular arc for the mouth, while the pie slices represent data grouped by sex, with distinct colors from the `d3.schemeCategory10` palette. The code uses `d3.pie()` for the arc generation and `d3.arc()` for rendering, with a button to trigger data transformations. The visualization runs entirely in SVG, with data loaded asynchronously via `d3.csv` and rendered through React hooks and the D3 selection API.

Donut Example

A donut chart displays five randomly generated numeric values as proportional arcs, with each slice labeled by its value in white text. The visualization updates its data on button press or when the data reference changes, demonstrating a React hook-based update pattern. Built with D3 v5 and React, the `Pie` component uses `d3.pie()` for arc generation, `d3.arc()` with configurable inner and outer radii, and a `scaleOrdinal` color scheme. SVG rendering occurs within a React component using `useRef` and `useEffect` hooks to manage the D3 selection lifecycle.

Donut of Rendering Data with React & D3

A donut chart displays CSS named colors as equal-sized slices, with each slice filled by its corresponding hex value. The entire donut rotates continuously, creating a slow animation driven by a React interval updating state. D3’s `arc` and `pie` utilities compute the slice geometries from CSV data loaded via `d3.csv`, while React renders the SVG paths. The visualization uses React hooks (`useState`, `useEffect`, `useRef`) to manage the animation loop and data fetching from a gist URL.

Rendering Data w/ D3 And React

This example renders a donut-style pie chart of CSS named colors using React and D3. The code fetches CSV data via `d3.csv` and employs `d3.pie` and `d3.arc` to compute and draw the SVG paths. Each slice is filled with its corresponding color value from the dataset, with React managing state and rendering the SVG elements.

React Starter with Pie

This example demonstrates a donut chart built with React and D3, displaying a small categorical dataset with five segments. It uses D3’s `pie` and `arc` functions to compute the angular positions and draw the SVG paths, while `scaleOrdinal` assigns a fixed color palette to each category. The chart is rendered inside a React component, with D3’s `select` and `append` methods managing the SVG elements directly within the React-rendered container. The code also includes a separate `useData` hook for loading CSV data, though the pie chart itself uses inline dummy data.

Untitled

This example shows a donut chart that visualizes a small dataset of five categorical values, with each slice colored distinctly and separated by black strokes. The chart uses D3.js version 6, where `d3.pie()` computes the arc angles from the data and `d3.arc()` generates the SVG path geometries with an inner radius creating the donut hole. A color scale via `d3.scaleOrdinal()` maps each category to a unique color, while the SVG rendering is sized and centered within a fixed 450×450 viewport. The slices are semi-transparent and rendered as SVG path elements appended to a grouped container.

Rendering data with React and D3

This example displays a full-color donut chart of CSS named colors, rendered as SVG paths. It uses React hooks (useState, useEffect) to asynchronously load the dataset from a CSV via d3.csv, then computes pie angles with d3.pie and draws arcs with d3.arc. Each slice is filled using the color’s hex value from the data.
