Fork of Vega-Lite API Template

This example displays a scatter plot of automotive data, with engine displacement mapped to the x-axis and horsepower to the y-axis, using a semi-transparent point mark for each vehicle. The visualization is built with the Vega-Lite API, which composes the specification and rendering through Vega and Vega-Lite, while D3 (d3.csv) fetches the auto-mpg dataset from a remote URL. The code also applies custom axis and label styling via a config object, and includes a Vega Tooltip handler for interactive hovering.

Fork of Vega-Lite API Template

This example shows a scatterplot of automotive data, mapping engine displacement to horsepower, with each point colored and labeled by car name. The visualization is built using the Vega-Lite API, with code that registers the vega, vega-lite, and vega-lite-api libraries, and uses vega-tooltip for interactive hover details. The data is loaded via d3.csv from a remote GitHub gist, and the chart is configured with custom axis styles and an opacity effect to reduce overplotting. The rendering targets an SVG output, sized to fill the browser window.

Fork of Mouse Follower

This example demonstrates mouse tracking by rendering a single circle that follows the cursor’s position across a 960×500 SVG canvas. The visualization, built with React and SVG, uses a `useState` hook to store the pointer coordinates, which are updated on every mouse movement via an `onMouseMove` event handler. The circle’s center is then re-rendered at the new `clientX` and `clientY` values, creating a direct, real-time interaction. The code relies on React’s state management and SVG’s declarative circle elements, with no external data source or processing.

Fork of Smiley Face Part V

Five identical smiley faces render in a row, each built from reusable React components that draw a yellow circle background, eyes, and an arc-based mouth. The code splits components across separate ES6 modules and uses React Fragments to group elements, while D3’s `arc` generator creates the mouth path and its `range` function supplies the face count.

Fork of Smiley Face Part III

This example shows a yellow smiley face rendered as an SVG, composed of a circular head, two eyes, and a curved mouth. It uses React to define the component structure and D3’s `arc` generator to create the mouth path, with the face centered and scaled relative to the viewport. The head is drawn with a filled circle and a thick black stroke, while the eyes are simple circles positioned via offset coordinates. The code leverages ReactDOM to mount the component onto a root element, with all dimensions hardcoded in the script.

Fork of Smiley Face Part II

This example renders a responsive smiley face using React as a component-based SVG visualization. The face is centered on the window and adapts its size and position to the viewport dimensions, with a yellow circle for the head, two black eyes, and a stroke outline. The code defines constants for eye offset, radius, and stroke width, then generates the SVG elements via React's declarative JSX syntax, relying on `ReactDOM.render` to mount the component. It uses no external data sources or animation, presenting a static, geometry-driven graphic.
