Rendering Data with React

Rendering Data With React D3

This example shows CSS named colors loaded from a GitHub Gist as CSV data, rendered as a vertical stack of thin horizontal bars whose background colors match each color’s hex value. Using React 17 hooks (`useState`, `useEffect`) and `d3.csv` for loading, it maps each row to a styled `div` element, displaying a loading message until the data arrives. The code also defines a separate `message` utility that reports the data’s approximate size, row count, and column count using `d3.csvFormat`.

A React component fetches CSS named color data as CSV using D3’s `csv` method and renders each row as a horizontal div whose background color corresponds to the hex value, creating a stacked spectrum. The example demonstrates declarative SVG-free rendering through React’s state hooks, with `useState` and `useEffect` managing asynchronous data loading and a loading state displayed as large text. The data comes from a GitHub gist of MDN’s named colors list.

Rendering Data with React

This example demonstrates how React can render data loaded with D3 utilities. It fetches a CSV file containing named CSS colors and their RGB hex values using `d3.csv`, then displays each color as a horizontal strip. The React component uses the `useState` and `useEffect` hooks to manage the asynchronous data loading, showing a "Loading..." message until the data arrives. Once loaded, the app maps over the data array to generate styled `div` elements, with each row’s background color set from the CSV’s `RGB hex value` column.

A color visualization renders the 148 CSS named colors as horizontal stripes, sorted in the order they appear in a CSV file loaded from a GitHub gist. The example demonstrates React’s component model by mapping each row of data to a `<div>` whose background color is set from the `RGB hex value` field. D3’s `csv` utility fetches and parses the data, while React’s `useState` and `useEffect` hooks manage the asynchronous loading state, showing a “Loading…” message until the data arrives. The result is a simple, full-width gradient-like display of all named colors in SVG-less, div-based rendering.

This example demonstrates a list of CSS named colors from a GitHub-hosted CSV file, rendered as horizontal color swatches. The visualization loads the data with `d3.csv` and uses React hooks (`useState`, `useEffect`) to manage state, while React components generate the visual output as styled HTML `<div>` elements. The code does not use SVG despite the page’s metadata; instead, each row becomes a colored block whose background is set via inline styles from the `'RGB hex value'` column, producing a full-width stacked spectrum. A loading message appears until the data is fetched.

Loading Data with React D3

This example demonstrates how to load and summarize a CSV dataset within a React application using D3. It fetches a list of CSS named colors from a GitHub Gist via D3’s `csv` function, then displays a text summary of the data’s size, row count, and column count. The rendering relies on React hooks like `useState` and `useEffect` to manage asynchronous data loading, while the `message.js` module formats the output using `d3.csvFormat` and `data.columns`. The visualization is a simple SVG-based preformatted text block, highlighting the integration of React and D3 for data fetching and display.

This example shows the color data from a CSV file of named CSS colors, rendering each color as a thin horizontal strip. The visualization loads the dataset with D3’s `csv` function and uses React’s `useState` and `useEffect` hooks to manage asynchronous data fetching. Each row is mapped to a styled `<div>` element with a background color derived from the `RGB hex value` column. The interface displays a “Loading…” message until the data arrives, and the code also defines a `message` utility that calculates the data size in kilobytes and row/column counts.

Loading Data with React & D3

This example demonstrates loading CSS named colors data from a GitHub Gist using D3’s `csv` utility, with React managing the asynchronous state via `useState` and `useEffect`. While fetching, the app displays a “Loading…” message; once the data arrives, it renders a summary showing the file size in kilobytes (computed with `d3.csvFormat`), row count, and column count. The visualization is purely textual, using React’s `message` helper and a styled `<pre>` element, with no graphical charts or custom rendering involved.
