This example displays a loading message while fetching a CSV file via D3’s `csv` function, then reports the file size in kilobytes, row count, and column count. Built with React hooks (`useState`, `useCallback`) and D3 v7, it renders the data summary inside a React component. The visualization itself is minimal, focusing solely on the asynchronous data-loading status and parsed dataset statistics.

This example displays the dimensions of a loaded CSV dataset, showing row and column counts alongside file size in kilobytes. It uses a React functional component with hooks (`useState`, `useEffect`) to fetch the data asynchronously via `d3.csv`, then formats the summary message with `d3.csvFormat`. The visualization renders as plain text within a `<pre>` element, with the React app bootstrapped through `ReactDOM.render` and D3 v6 included via CDN.

This example displays the file size, row count, and column count of a CSV dataset, dynamically updating the summary once the data finishes loading. It uses React hooks like `useState` and `useEffect` to fetch the data via `d3.csv`, and a helper function in `message.js` that leverages `d3.csvFormat` to calculate the size in kilobytes. The visualization is minimal, rendering a plain text message to the screen rather than any graphical chart, with the circle-following behavior absent from the provided code.

This example displays a loading message that reports the size, row count, and column count of a dataset loaded from a CSV file of CSS named colors. The code integrates React with D3 by using React hooks (`useState`, `useEffect`) to fetch data via `d3.csv`, then formats the summary with `d3.csvFormat`. The rendered text is plain, with no visualization beyond the data statistics.

This example loads a CSV dataset of CSS named colors using D3’s `d3.csv` utility and displays a summary of that data’s size, row count, and column count. The React application uses the `useState` hook to manage the fetched data, initially showing the text “loading” until the asynchronous request resolves. Once loaded, the message is rendered inside an HTML `<pre>` element, with the total file size computed via `d3.csvFormat`. The visualization is minimal, focusing on the data-loading and state-management workflow rather than graphical output.

This example displays a data summary for a CSV file containing CSS named colors, reporting the file size, row count, and column count once the data loads. The visualization uses React to manage state and render the text output, while D3.js handles the asynchronous CSV fetching and parsing from a remote GitHub Gist. The initial "loading" message is replaced by the computed statistics, demonstrating a minimal data-loading workflow.

Fork of Mouse Follower -- for Loading Data Section

This example demonstrates a React component that loads a CSV dataset and displays summary statistics about it in plain text. The application uses the `useState` and `useEffect` hooks to manage asynchronous data fetching, specifically calling `d3.csv()` to retrieve a list of CSS named colors from a GitHub gist. Once the data loads, the component renders the row count, column count, and file size in kilobytes, calculated using `d3.csvFormat()`. The visualization serves as a minimal, functional illustration of integrating D3 utilities with React state management for data loading workflows.

This example loads a named CSS color dataset from a remote CSV file and displays a summary of its size, row count, and column count. The React component uses the `useState` hook to store the data after fetching it asynchronously with d3.csv. The message is computed by formatting the CSV data back into a string with `d3.csvFormat`, measuring its length, and counting rows and columns. The interface shows only the text summary, with no graphic or interactive element beyond the loading state.

A React app loads a CSV of named CSS colors using d3.csv, then displays a text summary of the dataset’s size, row count, and column count via React state and the useState and useEffect hooks. The rendered message, built by the custom message function, formats the CSV size in kilobytes using d3.csvFormat. The example demonstrates integrating D3 data loading with React’s component lifecycle for simple asynchronous data visualization.
