Dataviz 2020_Ep16 - 10. Loading Data with React and D3

Loading Data with React & D3

This example demonstrates how to load and summarize a CSV dataset within a React application using D3 utilities. It displays the file size in kilobytes, number of rows, and number of columns from the CSS named colors dataset hosted on GitHub. The code uses the `useState`, `useEffect`, and `useCallback` hooks to manage asynchronous data loading, with the `csv` function from D3 fetching the remote data and storing it in React state. The resulting summary is rendered as text within a `<pre>` element.

Loading Data with React & D3

This example demonstrates how to load and summarize a CSV dataset in a React app using D3 utilities. It fetches CSS named colors data from a GitHub gist via `d3.csv`, stores the result in React state with the `useState` and `useEffect` hooks, and then displays a message showing the file size in kilobytes, row count, and column count. The `d3.csvFormat` function calculates the data size, while React renders the summary as text. The visualization uses D3 v7 and React 16.9 with no charting, focusing solely on data loading and state management.

Loading Data with React and D3

This example demonstrates how to load and summarize a CSV dataset in a React application using D3 utilities. The component displays the data’s size in kilobytes, row count, and column count in large text. React’s `useState` and `useEffect` hooks manage the asynchronous data loading, while D3’s `csv` and `csvFormat` functions fetch and format the data from a GitHub Gist containing CSS named colors. D3 version 5 and React 16 are used together.

Loading data with React and D3

This example demonstrates how to load and summarize a CSV dataset using D3 and React. The code fetches a list of CSS named colors via `d3.csv` and stores the result in React state with the `useState` and `useEffect` hooks. While loading, the display shows “loading,” then renders a message generated by `d3.csvFormat` that reports the data’s size in kilobytes, row count, and column count. React 16.9 and D3 v5 are used together, with the data sourced from a GitHub gist.

Loading Data with React and D3

This example demonstrates how to load and summarize a CSV dataset in a React application using D3. The interface displays a plain-text report showing the file size in kilobytes, row count, and column count. The code uses React’s `useState` and `useEffect` hooks to fetch data via `d3.csv` from a GitHub gist containing CSS named colors, then formats the result with `d3.csvFormat`. The SVG markup in the HTML file is commented out and unused.

Datavis 2020 Episode 16 - Loading Data in React

This example demonstrates how to load external data in a React application using D3 utilities, displaying file size, row count, and column count asynchronously. The app uses React hooks (`useState`, `useEffect`) to manage loading state and fetch a CSV file of CSS named colors from a GitHub gist. Once loaded, the `d3.csv` function parses the data, and `d3.csvFormat` calculates the data size in kilobytes for display. The interface shows a large text message before and after loading, with React re-rendering the output once the data arrives.

This example demonstrates how to load and display a summary of CSS named colors data using React state management and D3 utilities. The application fetches a CSV file from a GitHub gist using D3’s `csv` function, storing the parsed result in React’s `useState` hook via `useEffect`. While loading, it displays a simple "Loading..." message. Once data arrives, the view shows the file size in kilobytes, row count, and column count, formatted with `d3.csvFormat` and rendered as text in a `<pre>` element.

Loading Data with React & D3r

This example demonstrates how to load and summarize a CSV dataset within a React application using D3.js. It fetches the CSS named colors dataset from a GitHub gist, parses it with `d3.csv()`, and displays the file size in kilobytes, the number of rows, and the number of columns. The implementation uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, and `d3.csvFormat()` to compute the data’s string length. The result is rendered as plain text inside a `<pre>` element.
