Fork of Axes with React & D3

This example visualizes the top 10 most populous countries using a bar chart rendered with React and D3. It shows a horizontal bar chart with axes, displaying population data from the United Nations World Population Prospects 2019 dataset. The chart uses React hooks (useState, useEffect) to load and process CSV data, while D3's scaleBand and scaleLinear handle the y-axis country categories and x-axis population values. SVG elements, including rect bars, text labels, and grid lines, are generated through React components with manual axis construction rather than D3 axis generators.

Fork of Rendering Data with React & D3

This example visualizes the CSS named colors dataset as a radial burst, where each color is represented by a pie slice arranged around a central point. It loads the data from a CSV file using `d3.csv` and renders the visualization as SVG through React components. The code leverages `d3.pie` and `d3.arc` to compute the slice angles and paths, filling each path with the corresponding hex value from the dataset. React’s `useState` and `useEffect` hooks manage asynchronous data loading and trigger the rendering once the data arrives.

Fork of Smiley Face Part V

A React application renders a yellow smiley face with black outlines, featuring two eyes and a curved mouth on a blank canvas. The code splits UI components into separate ES6 modules—`BackgroundCircle`, `Eyes`, and `Mouth`—using React Fragments for grouping. It uses React 16.9, D3 v5's `arc` generator for the mouth path, and SVG for all drawing, with fixed dimensions and centered positioning via a `<g>` transform.

smile face I

A yellow smiley face rendered as SVG in a React component. The face consists of a large yellow circle with a black stroke, created by the `BackgroundCircle` component, and two small black circles for eyes. A mouth is drawn as a full circular arc using the D3 `arc()` API with an inner radius, resulting in a ring shape. The visualization positions all elements relative to the center of the SVG canvas using translation, with dimensions fixed at 960 by 500 pixels.
