Fork of Vega-Lite API Template

This interactive scatter plot explores the relationship between fuel efficiency and engine power across automobile models, with point size encoding weight and color encoding the region of origin. It loads Auto MPG data from the UCI Machine Learning Repository through a Gist URL via D3’s `csv` function. The visualization is built programmatically using the Vega-Lite API, which composes marks and encodings in JavaScript, then renders to SVG with Vega and adds tooltips via the vega-tooltip `Handler`. Custom axis and label styling come from a shared config object.

Fork of Vega-Lite API Template

This example shows a scatterplot of automobile displacement against horsepower, with opacity to reveal overlapping points and tooltips displaying car names. The visualization is built using the Vega-Lite API, which compiles specifications to Vega, and renders with D3.js’s CSV loader to fetch the auto-mpg dataset. The code customizes axes and text styling via a config object, and integrates Vega-Tooltip for interactive hover details.

Lets Make a Face: Part II

This example shows a smiling face built from basic SVG shapes: a yellow circle for the head, two smaller circles for eyes, and a curved path for the mouth. The face is rendered using React components that return an SVG element, with positions and radii defined as constants. D3’s `arc` function generates the mouth’s path by specifying inner and outer radii along with start and end angles. The visualization demonstrates how React and D3 can be combined to create simple, declarative graphics in an SVG canvas.

Let's Make a Face Part I

This example shows a simple yellow smiley face rendered as an SVG, with a large circular head, two small eyes, and a black outline. The face is drawn using basic SVG circle elements positioned relative to the center of a 960 by 500 viewport. The code uses React and ReactDOM to render the SVG structure, with hardcoded values for the head radius, eye offset, and stroke width. The visualization demonstrates how React can generate declarative SVG markup for straightforward geometric shapes.
