Exploring RDW data - Basic chart with filtering

This example displays a bar chart of parking facility capacities from Dutch RDW open data, with a checkbox filter that hides facilities with unknown capacity values. The visualization uses D3 v6 to render SVG bars, with a band scale for parking facility descriptions on the x-axis and a linear scale for capacity on the y-axis. Data loads from local test data (dataSelection.json) or a remote API via a CORS proxy. The interactive filter updates the chart by re-binding data, adjusting scales, and redrawing bars and axes using D3 selection methods. The chart uses rotated axis labels and a fixed height and width of 960 by 500 pixels.

D3 Map Nederland

This visualization displays an interactive map of Dutch municipalities, allowing users to click any region to zoom in and highlight it in red. Hovering turns municipalities orange, and clicking the background resets the view. Built with D3 v6 and TopoJSON, it uses a Mercator projection via `d3.geoPath` and implements zoom/pan with `d3.zoom`, applying smooth transitions through `transition.attrTween`. Municipal boundary data comes from a remote TopoJSON file fetched at runtime, rendered as SVG paths with animated scaling.

D3 Map Nederland

This interactive map of the Netherlands displays all municipal boundaries, which users can click to zoom in on and highlight in red, with pan and zoom controls supporting magnification up to 8 times. The visualization uses D3.js with `d3.zoom`, `d3.geoPath`, and TopoJSON to render the geographic data from a topojson file of 2020 Dutch municipalities. Hovering over a region turns it orange, while clicking resets the view or transitions the map using animated `transition.attrTween` effects.

Let's make a map with D3.js!

This example displays an orthographic map of the world, rendered as a blue sphere with grey country outlines. It uses D3’s `geoOrthographic` projection and `geoPath` to draw the sphere and country boundaries, pulling geographic data from the `world-atlas` TopoJSON dataset via `topojson.feature`. The SVG output includes a styled sphere fill and country paths, with interactive rotation not implemented in the shown code.

Lets make a face

A D3.js animation constructs a smiling face from basic SVG shapes: a yellow circle for the head, two circles for eyes, and an arc path for the mouth. The left eyebrow rectangle performs two sequential transitions, moving upward then returning to its original position. The code uses D3's selection and arc APIs, appending shapes to an SVG canvas with a translated coordinate system.
