Fork of Polished World Map

This example renders a polished orthographic world map using the d3 geo modules (`geoNaturalEarth1`, `geoPath`, `geoGraticule`) to draw country landmasses, interiors, and graticules as SVG paths. It loads country boundaries from the World Atlas TopoJSON dataset, applies a custom color scheme with teal land and gray graticules, and uses React to manage the data loading and render the visualization.

Fork of Axes with React & D3

This example displays the top 10 most populous countries as a horizontal bar chart labeled with axes. It uses React hooks (useState, useEffect) to fetch and load CSV data from the United Nations World Population Prospects 2019, then renders bars via SVG rectangles. D3’s scaleBand and scaleLinear position the bars, while manually generated ticks and labels create the x and y axes without d3.axis. The chart updates after loading, with React managing the component state and D3 handling the data scaling and formatting.

Fork of Rendering Data with React & D3

This visualization displays all CSS named colors as a radial burst, with each color represented as a wedge in a circle. The code uses React hooks to load the CSV data with d3.csv, then d3.pie and d3.arc compute the wedge geometries, while React renders each slice as an SVG path filled with the corresponding hex value. The example combines React’s declarative component model with D3’s data-joining utilities, rendering a full-color spectrum from the CSS color dataset.

Fork of Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization uses React with the `useState` hook to track mouse coordinates and rerender the circle’s `cx` and `cy` attributes. The app is built with React and ReactDOM, rendered into a full-screen SVG, with styling that hides page margins and scrollbars. The mouse movement is captured via an `onMouseMove` event handler on the SVG element.

Fork of Smiley Face Part III

A fork of the Smiley Face Part III builds a classic smiley face using React and D3 in a single SVG. The code renders a yellow circle for the head, two black eye circles, and a mouth arc created with D3’s `arc()` generator, all positioned via a central transform. React functional components handle the SVG structure, while D3’s arc API computes the mouth path with specified angles and radii. The static visualization uses fixed dimensions (960×500) and hard-coded coordinates for all facial features, with no interactive or animated behavior present.
