This example visualizes RGB color theory by stacking four semi-transparent rectangles—red, green, blue, and yellow—in a centered cluster to show how primary colors blend into secondary hues through overlap. Built with React and D3 v5, it uses reusable `MyRect` SVG components defined in a separate exports file. Each rectangle is positioned with explicit x/y coordinates and an opacity of 0.7, allowing the overlapping intersections to reveal mixed colors like cyan and magenta. The static SVG scene demonstrates subtractive color mixing without interaction, focusing purely on the visual result of layered transparency.

RGB color theory

Five overlapping semi-transparent squares demonstrate RGB color theory by mixing red, green, and blue primaries in various pairings to produce yellow, cyan, and a central white region. The React components `MyRect` and `MyCircle` render SVG rectangles with fixed opacity, positioned via translation transforms. Built with React 16.12 and D3 v5, the example uses static JSX coordinates rather than data-driven layout.

RGB color theory

Three overlapping translucent squares in red, green, and blue demonstrate RGB color theory through additive color mixing. Rendered as React components with SVG circles and rectangles, the visualization uses `MyRect` and `MyCircle` exports from `exports.js` to position three 250-pixel squares at offsets from the center of a 960×500 viewport with 0.9 opacity. D3 v5 sets the SVG dimensions while React 16.12 manages component rendering into the `#root` element.

RGB color theory

Three overlapping semi-transparent red, green, and blue squares form the classic RGB color-mixing diagram, revealing secondary colors where they intersect. The React components `MyRect` and `MyCircle` render SVG rectangles with configurable fill, opacity, and positioning, while D3 v5 supplies the scaling and layout logic in the background. Static SVG shapes are composed in a React component tree, with each square’s blend determined by a fixed opacity value of 0.9.

SVG Example

This example demonstrates basic SVG shapes arranged to show color blending through overlapping rectangles. The visualization uses three semi-transparent rectangles in red, blue, and yellow, which combine to create secondary colors where they intersect. The markup is hand-written SVG directly in the HTML file, with dimensions fixed at 500 by 500 pixels. The code also imports D3’s `select` function to update text content in the page, showcasing how D3 can complement pure SVG rendering.

Rendering Data with React

This example renders the full set of CSS named colors as a vertical stack of horizontal bars, each colored according to its hexadecimal value. The visualization uses React 18 with functional components and hooks (`useState`, `useEffect`) to manage asynchronous data loading, while D3’s `csv` utility fetches the color dataset from a GitHub gist. Once loaded, React maps each row to a styled `div`, setting the background color from the `Hex rgb` field. The visualization demonstrates how D3 can handle data acquisition and parsing while React manages the DOM rendering.

Rendering data with React

This example visualizes the 148 named CSS colors as horizontal stripes stacked into a block, with each stripe’s background color set directly from its RGB hex value. The visualization is built with React, which renders each color stripe as a styled `<div>` element, while D3’s `csv` method loads the color data from a GitHub gist. The app uses React’s `useState` and `useEffect` hooks to asynchronously fetch the data and display a "Loading..." message until it arrives.

Rendering data with React

This example visualizes CSS named colors as a stacked sequence of horizontal bars, each colored by its RGB hex value. Using React for rendering, it first loads the color data from a remote CSV file via D3’s `csv` utility and stores it in state. Once loaded, it maps over the data, creating a `<div>` for each color with the appropriate `backgroundColor` and fixed dimensions. The implementation combines React’s `useState` and `useEffect` hooks with D3’s data-fetching and parsing API, while also referencing a separate `message` module that computes file size, row, and column counts via D3’s format functions.

Rendering Data with React

This example displays CSS named colors as a vertical stack of horizontal strips, each colored by its RGB hex value. The data loads from a remote CSV file using d3.csv, and React state manages the asynchronous loading and rendering of the data into div elements. The visualization uses React 16.9, ReactDOM, and d3.v7, with SVG markup present in the HTML but the primary rendering approach relying on React’s component-based DOM updates.
