This example displays a loading screen followed by a vertical stack of colored horizontal bars, one for each CSS named color. The page initially shows a large “Loading...” message, then renders the dataset by mapping each color’s RGB hex value to a thin div’s background. The code uses React’s `useState` and `useEffect` to asynchronously fetch the CSS named colors CSV via D3’s `csv` utility, then maps the resulting array to styled divs with a fixed width of 960 pixels and height of 4 pixels each.

AI-generated description

A program that loads in some data about CSS named colors using D3 utilities, and uses React state to keep track of the data.

Fork of Fork of Loading Data with React & D3

This example visualizes CSS named colors as horizontal bars, with each bar’s background color set to the color’s RGB hex value from the dataset. It uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, and D3’s `csv` utility to fetch the color data from a GitHub gist URL. While the data is loading, the display shows the text “Loading...” in large font. Once loaded, the bars render in a vertical stack, demonstrating how React state updates trigger re-renders with D3-loaded data.

Fork of Loading Data with React & D3

This example displays CSS named colors as horizontal swatches stacked vertically, each rendered as a colored div. It fetches the CSS named colors dataset from a GitHub gist using D3’s `csv` utility, then stores the parsed result in React state via the `useState` and `useEffect` hooks. While the data loads, the interface shows a large “Loading…” message; once loaded, it maps each row to a div whose background color matches the row’s RGB hex value, creating a full-width color spectrum strip.

Fork of Loading Data with React & D3

This example displays all CSS named colors as horizontal stacked bars, with each color’s row showing its RGB hex value as the background. It uses React hooks (useState, useEffect, useCallback) to manage asynchronous state, while D3’s csv() function loads color data from a gist-hosted CSV file. The rendering approach maps each data row to a div element, dynamically setting its backgroundColor style from the parsed hex value, with a “Loading…” placeholder shown before data arrives.

Fork of Loading Data with React & D3

This example shows a vertical stack of colored horizontal bars representing CSS named colors from a CSV file, loaded via the `d3.csv` utility. The React `useState` and `useEffect` hooks manage the asynchronous data loading and trigger a re-render once the data arrives. Each row displays a bar with its background color set to the `RGB hex value` column. While the data loads, a simple "Loading..." message appears. The code uses React 16.9, D3 v5, and renders divs directly through `ReactDOM.render`.

Fork of Loading Data with React & D3

This example visualizes CSS named colors as a horizontal stacked bar chart, where each row represents a color by its RGB hex value. It loads color data from a CSV file using D3’s `csv` utility, then manages the asynchronous data fetching with React’s `useState` and `useEffect` hooks. While the data loads, a large “Loading...” message appears. The rendering maps each color entry to a div element with a fixed width and height, using the hex value as the background color. The code relies on React 16.9, D3 v5, and the `ReactDOM.render` method.

Fork of Fork of Loading Data with React & D3

This example renders a vertical stack of colored stripes representing CSS named colors. It loads the data from a CSV file using the `csv` function from d3-fetch, then uses React’s `useState` and `useEffect` hooks to fetch and store the data asynchronously. Once loaded, each row is mapped to a `<div>` whose background color is set from the `RGB hex value` column. The visualization demonstrates a simple data-loading pattern combining React state management with D3’s data utilities.

Fork of Loading Data w/ React with D3.

This example shows the CSS named colors dataset loaded asynchronously and rendered as colored bars, with a loading message displayed until the data arrives. The code uses React hooks (`useState`, `useEffect`) to manage data state and trigger the D3 `csv` utility to fetch the remote CSV file. Once loaded, each row is mapped to a `<div>` whose background color is set from the color value, demonstrating a simple integration of React’s declarative rendering with D3’s data-loading API.

Fork of Loading Data with React

This example demonstrates loading and displaying CSS named colors from a remote CSV file. It shows a vertical stack of colored horizontal bars, one for each color, rendered as HTML divs whose background colors are set using the RGB hex values from the data. The React app uses the `useEffect` hook to fetch the CSV with `d3.csv` and stores the result in state via `setData`, initially showing a "Loading.." message. The code uses React 17, ReactDOM, and d3.v7, with the data sourced from a Gist.
