This example displays a pie chart with four equal slices, each filled with a different color from a CSV dataset loaded via D3’s `csv` method. Built with React 18 and rendered as SVG, the chart uses `d3.arc` with an inner radius of zero and an outer radius of 200 to generate the paths. The slices are positioned by calculating start and end angles for each quarter, and hovering scales the arcs via CSS transitions. The data source is a static CSV fetched from a GitHub gist.

Pie chart using data loaded with React and D3

This example displays a pie chart where each slice represents a named CSS color from a dataset loaded via `d3.csv`. The chart renders as SVG using React components, with `d3.pie()` computing the arc angles and `d3.arc()` generating the path shapes. React state manages the asynchronous data loading, and each slice’s fill color directly uses the `RGB hex value` from the CSV data.

Pie Chart React & d3

A pie chart renders a color wheel from a CSV file of named colors, using React state to manage the asynchronous data loading. The static chart displays each color as an equally sized slice, with its fill set to the corresponding RGB hex value from the data. Built with React and D3 v7, the code uses `d3.csv` to fetch the data and `d3.pie` with `d3.arc` to generate the SVG paths. The visualization is rendered as an SVG element, centered on a 960x500 canvas.

D3 pieChart

This example displays a circular pie chart of CSS named colors, with each slice representing an equal share and filled using its own RGB hex value from the dataset. Built with React and D3 v6, the app loads CSV data via `d3.csv` and renders SVG paths using `arc()` and `pie()` generators. The chart is centered on a 960×500 SVG canvas, with slivers sized uniformly since `pie().value(1)` assigns a constant value to each entry.

Pie chart with react

A pie chart displays the relative frequency of named CSS colors, with each slice filled by its corresponding RGB hex value. The visualization loads CSV data via `d3.csv` and uses React's `useState` and `useEffect` hooks to manage asynchronous data fetching and component state. D3's `pie` and `arc` generators compute the slice geometry, which React renders as SVG `<path>` elements. The example demonstrates unidirectional data flow and mouse-event readiness within a React-D3 integration.

Pie chart

A pie chart displays the distribution of CSS named colors, with each slice colored according to its corresponding hex value. The visualization loads a CSV dataset using `d3.csv` and computes the pie layout with `d3.pie`, assigning each record an equal value. React renders the resulting arcs as SVG paths using `d3.arc`, positioned at the center of a 960×500 viewport. The chart uses D3 v5 and React 16.9, with all slices sharing a common radius and no inner gap.

Pie

This example shows a radial burst of colored arcs, each representing a CSS named color from a dataset loaded via `d3.csv`. The visualization renders a full circle of pie slices with no gaps, using React to manage state and render SVG paths. It leverages `d3.pie` to compute arc angles and `d3.arc` to generate the path geometry, with each slice filled using the color’s hexadecimal value from the data. The code demonstrates a hybrid approach where D3 handles data loading and calculations while React handles the DOM updates.

pie chart react

This example loads a CSV of CSS color names and their RGB hex values from a GitHub gist, then renders each row as a slice of a pie chart using React and D3’s `pie` and `arc` generators. The chart fills each path with the color’s hex value, producing a full circle of distinct hues. Data is fetched asynchronously with `csv` and stored in React state via `useState` and `useEffect`. The SVG output scales to the full window size, with the pie centered and a fixed outer radius of 250 pixels.

D3 piechart

This example shows a pie chart where each slice represents one named CSS color, loaded from a CSV file via `d3.csv`. The chart uses `d3.pie` to compute angles and `d3.arc` to generate SVG path strings, with each slice filled by its corresponding RGB hex value from the data. React manages the component state and renders the SVG, while D3 v7 handles the data loading and layout calculations, creating a colorful full-circle visualization of all named colors.
