Fork of Cheap Tricks for Interaction

This example shows an interactive world map that highlights countries in red on hover, with a blue ocean background. The visualization uses the `d3.geoNaturalEarth1` projection and `d3.geoPath` to render country boundaries from TopoJSON data, while a separate TSV file provides country names for tooltips. The map supports zooming and panning through the `d3.zoom` interaction module, which applies transform updates to the SVG group containing the paths. Countries are styled with CSS classes, and hover effects change their fill color using the `.country:hover` selector.

Fork of IMDb Movie ratings

This stacked bar chart shows the percentage of movie ratings across six genres, with each bar partitioned into five rating levels from “below 5.0” to “above 8.5.” Hovering over a segment reveals its exact percentage via a tooltip. The visualization uses D3 v7’s `d3.stack` to compute the stacked proportions and `d3.scaleOrdinal` for color encoding, rendering as SVG with axes from `d3.axisBottom` and `d3.axisLeft`. Data comes from a local CSV file summarizing IMDb rating distributions.

D3 Starter

This example demonstrates a minimal starter project for D3 version 7, rendering a static scene with an SVG circle, rectangle, and text element on a light gray canvas. The code loads the D3 library from a CDN and uses basic SVG drawing primitives such as `circle`, `rect`, and `text` with inline styling attributes, while the accompanying JavaScript file only prints a console message. The page centers the SVG, and the visualization illustrates how to set up an HTML page with embedded D3 and inline styles without any interactive or data-driven behavior.

Full Sol LeWitt Reproduction with D3 - exercises

This example reproduces a Sol LeWitt artwork using D3.js, rendering an SVG canvas that fills the browser window. It shows a grid of alternating horizontal and vertical stripes, with the stripes revealed through two distinct mask layers. The code uses `d3.select`, `d3.range`, `d3.symbols`, and `d3.symbol` to draw the geometric patterns and mask paths. The masks, created via the `renderMask` function, use inverted black-and-white fills and paths from `symbols` to selectively hide or show the stripes, producing the final composition.

SVG Fundamentals

This example demonstrates fundamental SVG shapes as a static gallery, including circles, rectangles, lines, and paths with varied fills, strokes, and coordinate positions. It shows the difference between filled, stroked, and unfilled shapes within a 1000x1000 viewport. The rendering is achieved through raw SVG markup embedded directly in the HTML, requiring no scripting or D3 functions for the visualization itself. The accompanying `index.js` file shows likely unused D3 imports and a local ES6 module, though these do not affect the visible graphic.
