Where the hexagons are rotated by 90.
While I painstakingly understood the concept of creating the topojson in Mike's example but to hack that code to produce this version of grid looks beyond my programming abilities :)
Will appreciate if someone can guide me how to achieve this.
Why I need this?
To create a cartogram for an upcoming state elections in India. I have the cartogram ready in illustrator. While I can export svg and control each polygon and achieve the results, using this grid will give far more control.
