De laatste decennia zijn zangvogels eerder gaan broeden, wellicht vanwege hogere temperaturen in het voorjaar. In dit figuur staat voor 44 zangvogels aangegeven waneer het eerste ei gelegd werd in de periode van 1986 tot en met 2014. Goed te zien is hoe deze vogels steeds vroeger in het jaar hun eieren leggen.

Creates a d3-voronoi diagram for a couple of random coordinates. The color of the polygons is defined by a continuous color scheme based on ColorBrewer using d3-scale-chromatic.
Example in D3 v4.0
For maps the EEA uses the ETRS_1989_LAEA_52N_10E coordinate system. This example shows how to get a similair projection with lat-lon data. The key parameters to get the right projection are:
The transverse Mercator projection
d3.geoTransverseMercator()
The center of the projection is on 10E 52N
projection.center([10,52])
