Fork of Loading Data with React & D3

This example displays a summary of CSS named colors data, showing the file size in kilobytes, the number of rows, and the column count. It loads the CSV data from a GitHub Gist using the D3 `csv` utility and React state to manage the fetched data. The interface toggles between a "Loading..." message and the data summary, rendered within a React component using the `useEffect` hook. The code also uses the D3 `csvFormat` function to calculate the data's size.

Fork of Loading and Parsing CSV Data

This example demonstrates how to load and parse a CSV file containing CSS Named Colors using D3 v5 and React. The page displays a summary of the dataset—its size in kilobytes, number of rows, and number of columns—in a large text element. The primary implementation uses `d3.csv` with promises, while commented-out alternatives show `fetch` with `async`/`await` and `d3.csvParse`, plus a nested promise structure illustrating the "pyramid of doom." The data comes from a GitHub gist hosted CSV file.

Fork of Smiley Face Part V

This example shows a yellow smiley face composed of a circular background, two eyes, and a curved mouth, all rendered as SVG elements in a React application. The visualization is built from separate ES6 module components, including a `BackgroundCircle`, `Eyes`, and `Mouth`. The code uses React (version 16.9) and D3’s `arc` API to generate the mouth’s path, with all shapes positioned relative to a central transform group. The static image uses hardcoded dimensions and coordinates, with no interactive or data-driven behavior.

Fork of Smiley Face Part III

This example shows a smiling face rendered as a scalable vector graphic, with a yellow circular head, two black eyes, and a curved mouth. The face is drawn using React components that produce SVG elements, while the mouth’s arc is generated with the D3 `arc` function, which specifies inner and outer radii and start and end angles. The code uses `d3` v5 and React 16, positioning the face elements relative to a central point via SVG transforms.

Fork of Fork of Smiley Face Part II

A yellow smiley face spans the full browser window, rendered with React components that generate SVG circles and a D3-generated mouth path. The face is built from separate SVG elements: a large yellow circle with a black stroke, two eyes with white highlights, and a mouth drawn using d3.arc with inner and outer radii for thickness. The layout positions all features relative to the viewport center. The example uses React 16.9 for component structure and d3.v7 for the arc shape, with no external data source.

Fork of Smiley Face Part II

This example shows a yellow smiley face drawn with SVG shapes, centered responsively to fill the browser window. The face includes two black eyes and a curved mouth, all rendered inside a React component that uses D3’s `arc` generator to create the mouth path. The SVG circle elements and the `arc`-based path are positioned via a `transform` translate group, with all dimensions computed from the viewport size. The code uses React 16.9, ReactDOM, and D3 v7, lighting the face with a yellow fill and black stroke.

Fork of Let's Make a Face Part I

This example shows a simple smiley face built from three SVG circles—a yellow head with a black outline and two eyes—rendered in a React component. It demonstrates how to use React to declaratively construct an SVG scene, computing positions with the constants `centerX`, `centerY`, `eyeOffsetX`, `eyeOffsetY`, and `eyeRadius`. The code uses ReactDOM to mount the component into the DOM, and the SVG elements are styled with attributes like `fill`, `stroke`, and `stroke-width`. No interactivity or animation is present beyond the static frame.

Smiley Face Part I

The visualization displays a partial smiley face, showing a yellow circle with a black outline and two smaller black-outlined circles as eyes, but no mouth. It represents an intermediate step toward a complete smiley face. The graphic is rendered as an SVG element with specific width and height attributes, using basic shape elements like circles positioned by their center coordinates. The HTML file contains inline CSS that removes page margins and hides overflow, allowing the SVG to fill the viewport without scrolling.
