This example uses React and D3 to load a CSV of Velib bike-sharing data and aggregate it by hour using `d3.rollups` with a sum of `num_bikes_available`. It then renders a scatter plot of circles with positions and opacity randomized on each render, sized by the summed bike counts. The SVG dimensions are 960×500, and the data pulls from a GitHub-hosted CSV. The app shows a loading message until the CSV parses asynchronously via `d3.csv`, after which it maps each group to a circle.

Loading Data with React & D3

This example demonstrates loading and visualizing a CSV dataset of bike availability from a GitHub-hosted file in a React application. It shows a scatterplot of randomly positioned circles, where each circle represents the total number of bikes available for a given hour, with the radius scaled by the summed value. The code uses React hooks (`useState`, `useEffect`) to fetch the data with D3’s `csv` method and `d3.rollups` to aggregate the dataset by date-hour. The circles are rendered as SVG elements, with random opacity and positions, displaying the processed data directly.

Fork of Loading Data with React & D3

This example demonstrates how React and D3 can work together to load and summarize a dataset of cars. The application fetches a CSV file from a GitHub gist using D3’s `csv` method and stores the parsed result in React state via the `useState` and `useEffect` hooks. Once loaded, it displays a text summary—computed with `d3.csvFormat`—showing the file size in kilobytes, the number of rows, and the number of columns. While the data is pending, the interface shows a "Loading..." message.

Fork of loading data with react and d3

This example demonstrates how to load and display CSV data in a React application using D3’s `d3.csv` method. It fetches a dataset of CSS named colors from a GitHub gist and stores the parsed rows in component state via React’s `useState` and `useEffect` hooks. The code includes a commented-out SVG visualization of circles, suggesting potential rendering with React elements, though no visual output is actively rendered. A utility function in `message.js` calculates dataset statistics like file size, row count, and column count using `d3.csvFormat`.

Fork of loading data with react and d3

This visualization uses React and D3 to load a CSV file of CSS color names and display a summary of its contents. The app fetches data from a GitHub gist via `d3.csv` and renders a message showing the file size in kilobytes, row count, and column count using `d3.csvFormat`. The interface is a bare HTML page with React 16 and D3 7, initially showing "Loading" until the asynchronous data fetch completes. The output is plain text within an SVG-capable document, though no graphical elements are drawn.

Fork of Loading Data with React & D3

This example demonstrates how to load and summarize a CSV dataset using React and D3. It fetches CSS named colors data from a GitHub gist via `d3.csv`, stores the parsed result in React state with the `useState` and `useEffect` hooks, and displays a loading message until the data arrives. The rendered output shows the data size in kilobytes, row count, and column count, computed using `d3.csvFormat`. The app uses React 16.9, D3 v5, and renders into a DOM root element.

Fork of Loading Data with React & D3

This example demonstrates how to load CSV data from a remote URL using D3’s `csv` utility within a React component. The React `useState` hook stores the fetched data, while `useEffect` triggers the asynchronous loading. The app displays a text summary of the dataset, including its size in kilobytes, row count, and column count, calculated with `d3.csvFormat`. The visible output is a simple `<pre>` element that shows either "Loading..." or the computed statistics, with styling from the linked CSS.

Fork of Loading Data with React & D3

This example demonstrates how to visually summarize a dataset of CSS named colors by displaying its size in kilobytes, row count, and column count as large text. It loads the CSV data from a GitHub gist using the D3 `csv` function, while React manages the asynchronous state with hooks like `useState` and `useEffect`. The app renders a loading message until the data arrives, then displays the statistics using a custom message function. The visualization integrates React 16.9 with D3 v5, showing how to combine both libraries for data-driven UI updates.

Fork of Loading Data with React & D3

This visualization demonstrates a minimal React and D3 integration that loads a CSV dataset of CSS named colors and displays its summary statistics. The app fetches the data using D3’s `csv` function within a React effect hook, then uses React state to manage the loaded data. Once fetched, the code formats a message with `d3.csvFormat` to report the file size in kilobytes, row count, and column count. During loading, the interface shows a “Loading...” message, and the final output is rendered as large monospace text using React’s `useState` and `useEffect` hooks.
