Forked from Clickable Circles with D3 Rosetta

This example demonstrates asynchronous data loading and parsing in a React-free D3 visualization, showing a loading indicator before rendering clickable circles from a CSV file. Using d3-rosetta's unidirectional data flow and `createStateField`, it manages state transitions from loading to succeeded or failed. When data arrives, `d3.csv` parses the x and y columns, then `renderCircles` draws circles that respond to clicks via `setupClickInteraction`, with `highlightSelectedDatum` visually distinguishing the selected point.

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 w/ React and D3

This example demonstrates how to load external CSV data with D3 and manage it through React state. The app uses `d3.csv` to fetch a dataset from a GitHub gist, storing the parsed result via React's `useState` and `useEffect` hooks. While the data loads, the screen displays “loading”; once available, a custom `message` function reports the dataset’s size in kilobytes, row count, and column count as large SVG text. The visualization is minimal, focusing on the integration of D3's data-loading utilities with React's component lifecycle.

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 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 and D3

This example demonstrates how React state can manage data loaded asynchronously with D3 utilities. The app uses `useState`, `useEffect`, and `useCallback` to fetch a CSV of CSS named colors via `d3.csv`, then displays a summary of the dataset as plain text. The message shows the file size in kilobytes, row count, and column count, computed with `d3.csvFormat`. Until the data arrives, the interface shows the word “loading,” illustrating a simple pattern for combining React’s component lifecycle with D3’s data-loading features.

Loading Data with React and D3

This example shows how React state manages asynchronous data loading from a CSV file of CSS color names. The app displays a text summary indicating the file size in kilobytes, row count, and column count. Using React’s `useState` and `useEffect` hooks, it calls `d3.csv` to fetch the remote dataset and stores the parsed result in state. While loading, the interface shows “Loading…”; once resolved, it passes the data to a helper function that computes the statistics using `d3.csvFormat`. The visualization renders as plain text within a `<pre>` element.

Loading Data with React

This example demonstrates a hybrid React and D3 workflow for loading and summarizing a CSV dataset. It uses the D3 `csv` utility to fetch data from a remote URL and React state to manage the asynchronous result. The app displays a loading message until the data arrives, then renders a text summary showing the file size in kilobytes, row count, and column count, all computed using D3’s `csvFormat` function. The rendering is a simple SVG-less HTML `<pre>` element, highlighting data loading rather than visual encoding.

Loading Data with React and D3

This example demonstrates loading a CSV dataset into a React component using D3’s `d3.csv` method, fetching CSS named colors from a GitHub gist. Once the data arrives, it is stored in React state via the `useState` hook, and the raw data object is displayed directly in the DOM. The visualization renders as SVG, with the React app mounted into a root div, showing the asynchronous data-loading pattern in a minimal interface. The code highlights integration of D3’s data fetching with React’s component lifecycle.
