This visualization displays a single choropleth-style map of the Netherlands, showing generalized administrative regions for 2019. It uses a Mercator projection to render geographic boundaries as SVG paths. The code relies on D3.js v3, specifically `d3.geo.mercator` for projection and `d3.geo.path` to draw the shapes, while fetching GeoJSON data from the Dutch national geodata WFS service. The map is rendered on a 1200×500 pixel canvas with no additional styling or interaction.

Voorbeeld 1

This example shows interactive maps of the Netherlands, centered on Groningen, with a marker and popup identifying the Martinitoren. It demonstrates three versions of Leaflet-based mapping: the first displays a standard tile layer; the second adds a layer control to switch between five Dutch base maps (standaard, grijs, pastel, water, luchtfoto); the third uses a custom projected coordinate system (EPSG:28992) via Proj4Leaflet to load an OpenTopo background tile layer. The code uses Leaflet’s tile layer, marker, popup, and control layers, with tile sources from PDOK and OpenTopo.

This example shows a choropleth-style map of Dutch police districts, with hover interactions that reveal the district name in a tooltip. The visualization loads geographic boundary data from a national geo-service via WFS, processes it with Turf.js to rewind polygon coordinates, and renders it as SVG paths using D3’s geoMercator projection and geoPath. Hovering a district turns it orange and displays a floating label, while mouseout fades the tooltip away. The code relies on D3 v3 for SVG manipulation and event handling, with Turf.js for geometry correction before projection.

Arrondissementsgebieden

This example visualizes Dutch judicial districts as interactive map shapes, highlighting each region on hover. It shows administrative boundaries sourced from a national geodata WFS service, with tooltips displaying district names. The code uses D3 v4’s `d3.geoPath` and `d3.geoMercator` projection, alongside Turf.js to rewind GeoJSON polygons for correct rendering. SVG paths change fill color on mouseover, while a custom HTML tooltip follows the cursor, all within an animated, zoomable viewport.

This example shows a static map of Dutch arrondissements (districts) for 2019, rendered as a single SVG path using a Mercator projection. The code loads GeoJSON data from a national georegister Web Feature Service (WFS) endpoint via `d3.json`. It uses `d3.geo.mercator` and `d3.geo.path` to project and draw the geographic features. The visualization is minimal, displaying only the district boundaries without additional styling or interactivity.

ZONDER TURFFFFF

This example displays a static map of Dutch arrondissementsgebieden (judicial districts) for 2019, rendered as SVG paths using D3 v4. It shows the geographic boundaries of these administrative regions, projected with a Mercator projection and fitted to a 700×400 viewport. The code fetches GeoJSON data from a Dutch national geodata WFS service, then uses `d3.geoPath` and `d3.geoMercator` to draw the features. The visualization emphasizes the shape and relative location of the districts without interactive or animated elements.

This visualization shows a TopoJSON map of Dutch administrative regions, rendered as vector shapes defined by coordinate arcs. The data file, named "arrondissementsgebieden.json" (Dutch for "districts areas"), contains geospatial boundary data that is displayed as a static map. The arcs encode the outlines of the regions, and the visualization likely uses D3.js or similar to project and render these coordinates as an interactive or static choropleth-style map, though no styling or color encoding is present in the raw data. The example demonstrates how raw topological data can be parsed and displayed as a map of regional boundaries.

This visualization shows a map of Dutch municipalities (gemeenten) rendered from a TopoJSON topology file. The SVG-based map uses D3 v4 to draw geographic boundaries, with each municipality outlined as individual paths. The animation animates the paths when the visualization loads, drawing the boundaries in sequence. The data source is a TopoJSON file containing the geometry of the Dutch municipal divisions, which is loaded and converted for display. The visualization highlights the boundaries between municipalities across the Netherlands, with the animated drawing effect emphasizing the shapes and spatial relationships of the regions.
