This example demonstrates asynchronous data loading in a React application using D3 v6. It fetches a CSV file of CSS named colors from a GitHub gist via `d3.csv()` and displays either a loading message or a data summary through a React state hook. The code uses `useState` and `setData` to trigger re-rendering when the promise resolves, while a secondary helper parses the fetched text with `d3.csvParse()` to show file size in kilobytes.

Loading Data

This example demonstrates asynchronous data loading with D3 and React. It fetches a CSV file of CSS named colors from a GitHub gist, then displays the file size, row count, and column count as plain text. The code uses React hooks (`useState`, `useEffect`) to manage state and trigger the `d3.csv` request, while a helper function formats the statistics from the parsed data. Rendering switches from a “loading…” message to the dataset summary once the promise resolves.

d3 & react: loading data

This example demonstrates how to load CSV data with D3 and manage it using React state. The app fetches a dataset of CSS named colors from a GitHub gist via `d3.csv`, stores it in React's `useState`, and renders a summary message with `d3.csvFormat` displaying file size, row count, and column count. While the data loads, it displays "Loading...". The integration uses React hooks (`useEffect`, `useState`) alongside D3 v6 utilities.

Loading Data with React & D3

This example demonstrates how React state manages data loaded asynchronously with D3. It fetches a CSV file of CSS named colors from a GitHub gist using `d3.csv` and stores the result in state via `useState` and `useEffect`. Once loaded, the app displays a text summary of the dataset, including file size in kilobytes, row count, and column count, computed with `d3.csvFormat`. While loading, it shows a “loading…” placeholder. The visualization is purely textual, highlighting the integration of D3’s data-loading utilities with React’s component life cycle.

Loading data with React & D3

A React application demonstrates asynchronous data loading with D3, using React state to track whether a CSV dataset is loaded. The app fetches CSS named colors from a GitHub gist via `d3.csv` and stores the parsed result in React's `useState` hook. The interface displays a simple text indicator that changes from "loading" to "loaded" once the data arrives. The example uses React 16.9, D3 v6, and renders only a plain text message rather than any SVG visualization, with the SVG markup present in the HTML file commented out.

Loading data with D3

This example demonstrates asynchronous data loading in a React application using D3. It fetches a CSV file containing CSS named colors, then displays a summary message showing file size, row count, and column count once the data arrives. The implementation uses React hooks (`useState` and `useEffect`) to manage state and trigger the `d3.csv()` request, while a helper function calculates and formats the data metrics. The visualization renders as pure SVG text, with a loading state displayed before the data is fetched.

Loading Data with React and D3

This example demonstrates how to load and summarize CSV data asynchronously using React and D3. It fetches the CSS named colors dataset from a GitHub gist via D3's `csv` function, storing the result in React state with the `useState` and `useEffect` hooks. The rendered view displays a plain-text summary of the loaded data, including size in kilobytes, row count, and column count, calculated using `d3.csvFormat`. Until the data arrives, a “loading” message appears.

Loading data with react and D3

This example demonstrates how to load external CSV data using D3 utilities within a React application. It fetches a dataset of CSS named colors from a GitHub gist and displays summary statistics about the data, including file size in kilobytes, row count, and column count. The React `useState` and `useEffect` hooks manage the asynchronous data loading, while `d3.csv` and `d3.csvFormat` handle parsing and formatting. The result is rendered as SVG text showing either a loading message or the computed data metrics.

Loading Data with React and D3

This example demonstrates loading external data with D3 utilities while managing it through React state. The application fetches a CSV file containing CSS named colors from a GitHub gist, then displays a summary of the loaded dataset, including file size in kilobytes, row count, and column count. It uses React’s `useState` and `useEffect` hooks to handle the asynchronous data loading, along with `d3.csv` for parsing, `d3.csvFormat` for measuring data size, and `ReactDOM.render` to mount the component. The interface initially shows a "Loading" message before presenting the computed statistics.
