This example demonstrates loading a remote CSV dataset with d3.csv in a React application, displaying the file size, row count, and column count in a large text element. A black SVG circle follows the mouse cursor across the viewport using React’s useState and useCallback hooks to track and update the pointer’s clientX and clientY coordinates. The code imports React and ReactDOM, creates an SVG with dimensions 960 by 500 pixels, and sets the circle’s center to the current mouse position. The CSV data comes from a GitHub gist containing named CSS colors.

Mouse Follower with data

This example demonstrates loading a CSV dataset with D3 and displaying the loading status through a React component. It shows how D3’s `csv` function fetches data from a remote URL containing CSS color names, while React’s `useState` and `useEffect` hooks manage the asynchronous state. The visualization renders a text message as an SVG element, displaying the number of rows and columns once loaded, updating from "loading..." as data arrives. The project combines React 16.9, D3 v7, and uses a plain HTML pre tag for text output rather than a chart.

Loading data in React & D3 -- Fork of Mouse Follower

This example demonstrates how to load and display a CSV dataset within a React application using D3.js. The interface initially shows a "Loading..." message, then presents the fetched data in a formatted table using `d3.csvFormat`. The data is retrieved asynchronously from a GitHub gist containing CSS named colors. The implementation relies on React's `useState` and `useEffect` hooks to manage the data state and trigger the fetch operation exactly once, using `d3.csv` to parse the remote CSV file.

Loading Data with React & D3

This example demonstrates loading a remote CSV dataset using D3’s `csv` method within a React component, displaying the data’s size, row count, and column count as text. The `useState` and `useEffect` hooks manage the asynchronous data loading, rendering a “loading...” message until the promise resolves. The application uses React 16.9, D3 v6, and SVG-free output, presenting the metrics in a large `<pre>` element. The data come from a GitHub gist containing CSS named colors.

Loading data with React and D3

This example demonstrates loading a remote CSV dataset with React and D3, displaying the file size, row count, and column count as text. The `useState` and `useEffect` hooks manage asynchronous data loading, while D3’s `csv` fetches the CSS named colors data from a GitHub gist. The message is generated with `d3.csvFormat` to calculate byte size, and rendered as large text in an SVG-free `<pre>` element. React 16.9 and D3 v5 handle the data pipeline and rendering.

Loading Data with React and D3

This example demonstrates how to load a CSV dataset in a React application using D3 utilities, displaying the data’s size, row count, and column count in a large text block. It uses the `useState` and `useEffect` hooks from React to manage the loaded data, and `d3.csv` to fetch the CSS named colors dataset from a GitHub gist. The file size is computed with `d3.csvFormat`, and the rendering is done through SVG.

Loading Data with React and D3

This example demonstrates how to load and summarize a CSV dataset in a React application using D3. It displays the file size, row count, and column count of a CSS named colors dataset fetched from a remote URL. The code uses D3’s `csv` function to load the data and `csvFormat` to calculate its size, while React’s `useState` and `useEffect` manage the asynchronous state. The result is rendered as SVG text within a `<pre>` element, initially showing “Loading” until the data arrives.

Loading data with React & D3

A React and D3 example demonstrates asynchronous data loading by fetching a CSV of CSS named colors and displaying a summary message with file size, row count, and column count. The application uses React's `useState` and `useEffect` hooks to manage the data-fetching lifecycle, calling `d3.csv()` to parse the remote CSV file. Once loaded, the data is transformed through `d3.csvFormat` and rendered as SVG text. The visualization also includes a separate smiling face composed of reusable React components—`BackgroundCircle`, `Eyes`, and `Mouth`—where the mouth is drawn using D3's `arc()` path generator with specified angle parameters.

Loading Data with React & D3

This example demonstrates loading and displaying CSV data in a React application using D3’s `csv` method. It fetches a remote CSS color dataset from a GitHub gist, then formats the results to show the number of rows, columns, and file size in kilobytes within a preformatted text block. The React `useEffect` hook triggers the asynchronous data fetch, while `useState` manages the loading state, rendering “Loading…” until the data arrives. The output is styled with a large font and displayed as SVG, though the SVG markup is commented out.
