Sized Points on a Map

This visualization displays a world map with circles sized by city population, using a square-root scale to encode magnitude. The map includes landmasses, graticules, and country interiors rendered via d3.geoPath and a geoNaturalEarth1 projection. City coordinates and population data come from a CSV dataset, with React managing the component lifecycle and d3.v5 handling data loading and scaling. Semi-transparent teal circles are positioned using the projection and scaled up to a maximum radius of 15 pixels.

Sized Points on a Map

This visualization displays a world map with points sized proportionally to city populations, showing cities with over 50,000 residents. It uses d3.geoNaturalEarth1 for projection and d3.geoPath for rendering country boundaries and graticules. City coordinates and populations come from a CSV loaded from Simplemaps, while country shapes use TopoJSON from World Atlas. The point radii are scaled with d3.scaleSqrt, and React manages component rendering.

Let's make a face with D3.js!

A smiling face made of SVG shapes demonstrates fundamental D3.js DOM manipulation. The code selects an SVG element and appends yellow circles for the head and eyes, black rectangles for eyebrows, and an arc-based path for the mouth. Using `d3.transition` with a two-second duration, the eyebrows animate upward and then back down, creating an expressive movement. The example uses D3 v5's `select`, `append`, and `attr` methods to build and update elements, with the mouth drawn via `d3.arc`.

Hello VizHub

This example demonstrates basic SVG shape rendering and styling within a static HTML page, using D3.js as the sole imported library but leveraging standard SVG elements for the visualization. It shows circles, rectangles, lines, and a path, with groups applying stroke and fill properties to coordinate multiple shapes. The code imports a message from a local ES6 module, `myMessage.js`, and uses `d3.select` to update the page text. The `styles.css` file imports the Ubuntu font and defines classes for line and path styling, while the SVG is rendered client-side with no external data source.
