This example demonstrates how to load multiple asynchronous resources before rendering content to a canvas, using `d3.queue` to coordinate a text file and an image. The code defines a custom `d3.imageload` function that wraps the HTML `Image` object, then defers both it and `d3.text` for `hola.txt` and `thumbnail.png`. After both complete, it displays a status message and draws the loaded image onto the canvas using the Canvas API’s `drawImage` method. The page’s body is fixed to fill the viewport, and rendering targets a `canvas` element.

Built with blockbuilder.org, but unfortunately it does not work within Blockbuilder (#186).

Asynchronous Queue

This example demonstrates asynchronous loading and summation of three remote JSON files using the d3-queue library with a concurrency limit of two. A large headline displays the formula “1 + 2 + 3” and updates the result from “?” to the calculated sum once all files are fetched. The code uses `d3.queue(2)`, `d3.json` deferrals, and an `awaitAll` callback to render the computed total via `document.querySelector`. Data files `1.json`, `2.json`, and `3.json` each contain a single number, which are combined with a `reduce` function.

load image

A single image loads inside an SVG canvas and is positioned at the top-left corner of a 960-by-500 pixel viewport. The example demonstrates a minimal D3 v4 setup using the `d3.select` and `svg.append("image")` methods to embed a JPEG file via the `xlink:href` attribute. The image is fixed at 200 pixels wide and 200 pixels tall, with no scaling, animation, or interaction. The code relies on the standard D3 selection and append API, rendering the graphic as static SVG output.

Loading data in D3

This example demonstrates asynchronous data loading and rendering in D3 with a React front end. It fetches a CSV file of named colors from a GitHub gist using the `d3.csv` API, displaying each row as a colored `<div>` block once the data arrives. The page initially shows a "loading..." placeholder until the promise resolves, then maps each CSV entry to a styled HTML element whose background color is set from the `color` field. The code uses React hooks (`useState`, `useEffect`) to manage state and trigger the D3 request.

loading data d3

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 with React & D3

This example demonstrates asynchronous data loading in a React component using D3’s `csv` function to fetch a named-color dataset from a GitHub gist. The app renders a text summary displaying the data size in kilobytes, row count, and column count once the CSV arrives, with a loading message before completion. It uses React hooks (`useState`) to manage state and invokes `d3.csv` within the component. The visualization is minimal, showing only a `<pre>` element with dynamic text, originally intended to accompany a "following circle" SVG sketch visible in the HTML comments.

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 React & D3

This example demonstrates how React manages asynchronous data loading for D3 visualizations. The app uses React’s `useState` and `useEffect` hooks to fetch a remote CSV file via D3’s `csv` method, displaying a loading message until the data arrives. Once loaded, a custom `message` function computes and renders the file size in kilobytes, row count, and column count using `d3.csvFormat` and the data’s `columns` property. The result is shown as plain text in a `<pre>` element, highlighting the integration of D3’s data parsing with React’s component lifecycle.

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.
