This example shows a choropleth-style map of Dutch police districts (arrondissementen) from 2019, highlighting each region on hover with an orange fill and a text tooltip that reveals the district’s name. The visualization relies on the D3 v4 library, using `d3.geoMercator` for projection and `d3.geoPath` to render the GeoJSON features fetched from the Dutch national georegister WFS service. The tooltip appears near the cursor via D3’s event handling, while the SVG paths are drawn with a light gray fill and white strokes, with hover interactions triggering the color change and tooltip display.

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.

Zonder turf in d3v3

This example shows a choropleth-style map of Dutch arrondissements, with hover highlighting in orange and a tooltip. It uses D3 v3 with a Mercator projection and `d3.geo.path()` to render GeoJSON features as SVG paths. The map loads data from a public WFS service, styling regions with light gray fills and white strokes. The code explicitly sets the projection’s translate but leaves the scale at its default, so the map may appear cropped or misaligned. A CSS tooltip is defined but not implemented in the script.

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.

arrondissementen in d3.js v3

This example visualizes Dutch administrative arrondissementen using a web Mercator projection. It shows a single combined path of the geographic boundaries, retrieved from a national georegister WFS service as GeoJSON, and renders it as an SVG path. The code uses d3.v3's `d3.geo.mercator()` for projection and `d3.geo.path()` to convert the GeoJSON features into a scalable vector graphic. A hardcoded scale parameter triggers an alert before the map is drawn, highlighting the projection’s default scale setting. The visualization focuses solely on the raw boundary shapes without additional styling or interaction.

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.

D3 Map Nederland

This example displays an interactive map of Dutch municipalities, coloring each region in light blue with black outlines and highlighting areas in solid blue on hover. The visualization loads geographic data from a TopoJSON file and renders it as SVG paths using D3 v5 with a Mercator projection. It employs d3.json to fetch the data, d3.geoPath with geoMercator for drawing shapes, and includes d3-zoom.v2 for potential panning and scaling capabilities. The hover effect is implemented through CSS, and each municipality includes a tooltip showing its name and ID.

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.
