Hi there Simon, With enough elbow grease, you can do a lot with D3 - even recreate much of what Leaflet does. A tabular layout for hierarchical data, indented trees allow one or more columns of values to be shown alongside indented names. Compute the Voronoi diagram of a set of two-dimensional points. geoInterpolate to interpolate a path along great arcs, and spherical linear interpolation to rotate the orthographic projection. These contours are computed in equirectangular coordinates and then reprojected. Visit D3 . This matrix shows Kristen Gorman’s data on penguins near Palmer Station in Antarctica.

The tour zooms in on each cluster’s bounding box in succession before zooming back out to the overview. A specialized x-axis is used to avoid gaps on the weekend when the markets are closed. The implementation allows brushing to select data points in one cell, and highlight Is there a way to import the standard d3 bundle together with d3-selection-multi? The advice in this thread works for requiring d3-selection and d3-selection-multi, but require('d3', 'd3-selection-multi') doesn’t seem to work even though d3-dsv supports automatic type inference. 2 Likes. The following chart of the phases of the Moon uses two such scales: the first positions the day vertically, by month (on a 12-point scale); the second positions it horizontally by day. ascending returns the natural order of a given value a relative to a given value b. counties as of August 2016. 6 stars. We don’t use automatic type inference (`{typed: true}`) as that would coerce the FIPS identifiers to numbers, which then wouldn’t match the identifiers in our GeoJSON. For a more elaborate solution with a gradient encoding, see this notebook. A “cluster” force attracts each group of nodes towards its weighted centroid, while a “collide” force prevents nodes from overlapping. group and d3. Plot is built by the same team as D3. Point scales allow to distribute an array of points equally into a given range interval. A path’s shape is specified in the SVG path data language (or D3.
