Fork of Choropleth Map with Interactive Filtering

This choropleth map visualizes countries colored by economy category using a natural Earth projection. Users can click legend items to filter the map, highlighting matching countries while dimming all others, and can also zoom and pan the SVG view. The visualization uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom for map rendering, with a d3.scaleOrdinal and schemeSpectral for color encoding. It loads geographic and metadata from the World Atlas TopoJSON and TSV datasets, while the color legend enables interactive filtering through click handlers.

Fork of Choropleth Map

This choropleth map colors countries by economic classification using a natural Earth projection with an ordinal spectral color scale. The visualization supports zooming and panning through d3.zoom, with country names and income groups revealed on hover via SVG title elements. A custom color legend with circles and text labels is built using D3 data joins, while geographic data comes from the world-atlas TopoJSON dataset processed with topojson.feature and loaded via d3.tsv and d3.json. The map is rendered entirely in SVG.

Fork of Mouse Follower that Changes Color

A circle follows the mouse across an SVG canvas, changing color with each click. The visualization uses D3's `select`, `selectAll`, and `join` methods to declaratively manage the SVG circle element, tracking mouse position and color state in an external `state` object. Rendering is driven by unidirectional data flow: `setState` updates the state and triggers a re-render, which applies the new `cx`, `cy`, and `fill` attributes to the circle.

Fork of D3 Scatter Plot

This fork of a D3 scatter plot visualizes the Iris Dataset, mapping petal length on the x-axis and sepal length on the y-axis. It loads CSV data from a Gist URL using `d3.csv` and renders circles as SVG marks. Axes are drawn with `d3.axisLeft` and `d3.axisBottom`, while `d3.scaleLinear` and `d3.extent` compute the scales. The chart fills the browser window, using `window.innerWidth` and `window.innerHeight` for its dimensions.
