d3 color scale from ncar ncl color table
I am interested in an easy way to generate a color table with a defined number of colors for use with this:
http://andreasplesch.github.io/x3dom/GeoElevationGrid_texture/terrain_spheresensor.xhtml
Here is a D3 way to use the many color maps NCAR's NCL provides. The original source file is read, so all of the parsing and then color scale (mapping) work takes place in the callback. The original tables directly map to D3 linear scales with a segmented definition. Hcl interpolation looks better for oversampling. The resampling is then simply an application of a new input domain to the piecewise color scale function. Since I use table cells to draw the color tables, there is a somewhat clever function to keep the table at a constant total width by inserting an extra width pixel every so many columns.
These are some tests to check behavior of the d3 range() method when it is used with fractional step sizes.
https://github.com/d3/d3-arrays has the candidate versions for a new release d3. The range() function below is copied over from there.
