A React hook-based pie chart example demonstrates how to render D3-generated SVG arcs with state-managed data updates. Using `useState` and `useEffect`, the app generates random numeric data with `d3.range` and `Math.random`, then passes it to a `PieSvg` component that computes arc paths via `d3.pie()` and `d3.arc()`. A button click triggers `setData` to regenerate values, while a separate `ColorLegend` component renders interactive colored circles with hover effects that fade non-hovered ticks using opacity. The visualization shows D3-created SVG elements managed entirely by React’s render cycle.

D3 and React Hooks

Two pie charts render identical datasets side by side, each taking a different approach to integrating D3 with React function components. The first, PieSVG, lets React fully manage the SVG lifecycle, mapping data arcs to JSX elements. The second, PieHooks, uses `useEffect` and `useRef` to imperatively manipulate the DOM with D3 selections like `selectAll`, `enter`, and `merge`. Both use `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate and style the arcs, with random data regenerated on button click.

Fork of Redndering data with React

A React application renders a pie chart of CSS named colors as SVG paths, using D3 to load the CSV data and compute the arc geometry. The code employs the React `useState` and `useEffect` hooks to fetch the data asynchronously and update the chart once loaded, while `d3.arc` and `d3.pie` handle the circular layout. Each slice is filled with its corresponding color hex value from the dataset, demonstrating a simple integration of D3 utilities within a React component.

This example renders a dataset of CSS named colors as a pie chart, with each slice colored by its corresponding RGB hex value. The visualization loads the data from a CSV file using `d3.csv` and manages the asynchronous state with React’s `useState` and `useEffect` hooks. React renders the SVG paths, while D3’s `pie` and `arc` generators compute the slice angles and path geometry. The chart is centered using an SVG `<g>` transform, and the code includes commented alternatives for manual arc computation.

Fork of Rendering Data with React & D3

This example shows a radial burst of the CSS named colors, with each color represented as a slice of a pie chart. It uses React hooks like `useState` and `useEffect` to asynchronously load the data with `d3.csv`, then renders SVG paths via React. The `d3.pie` and `d3.arc` APIs compute the angular layout and path geometry, while the fill color comes from the `RGB hex value` column. The visualization transitions from a loading message to the full color wheel once the data arrives.

This example renders a pie chart of CSS color names loaded from a CSV file, with each slice filled by its corresponding RGB hex value. The code uses React hooks (`useState`, `useEffect`, `useCallback`) to fetch and store the data, then creates the chart with d3’s `pie` and `arc` functions. The SVG is rendered through ReactDOM, with the `pieArc` generator set to an outer radius equal to the chart width.

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 of Fork of Fork of Rendering Data with React & d3

A radial burst of CSS named colors, rendered as a pie chart where each wedge represents one color from a dataset loaded via `d3.csv`. The React component uses the `useEffect` hook to fetch the data, then `d3.pie` and `d3.arc` compute the wedge geometry, which React renders as SVG `<path>` elements. The fill of each path is set directly from the color’s hex value, creating a full circular spectrum. The visualization demonstrates combining D3’s data-joining utilities with React’s declarative component rendering.

The code loads color data from a CSV file using D3’s `csv` utility, then uses React’s `useState` and `useEffect` hooks to fetch and store the data. D3’s `pie` and `arc` generators compute the slice geometry, while React maps each data entry to a colored `<path>` element. The visualization demonstrates a hybrid approach where D3 handles data loading and layout calculations, and React manages the DOM rendering.
