Fork of Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The visualization uses React 16.9 with the `useState` and `useCallback` hooks to manage and update the circle's coordinates. The SVG element handles the `onMouseMove` event, and the circle's center is set via the `cx` and `cy` attributes, rendering at a fixed 30-pixel radius on a 960-by-500 viewport.

Fork of Vega-Lite API Template

This example demonstrates how to build interactive visualizations using the Vega-Lite API within a D3.js framework. It displays a line chart of automobile data from a CSV file, plotting horsepower over time with a viridis color scale and tooltips showing vehicle names. The visualization leverages the vega-lite-api library to construct the chart declaratively, while D3’s csv function loads the data. Custom configuration adjusts axis styling and font sizes, and the final SVG output is rendered across the full viewport with auto-sizing.

Fork of Vega-Lite API Template

This example visualizes the relationship between engine displacement and horsepower for a set of automobiles, with tooltips revealing the car name for each point. The visualization is built using the Vega-Lite API, which composes a scatter plot using `vl.markPoint()` with `fieldQ` encodings for the quantitative axes. Data is loaded asynchronously from a CSV file containing the auto-mpg dataset via `d3.csv`. The chart is rendered as SVG, with custom axis styling defined in a config object and interactive tooltips supplied by the vega-tooltip handler.
