描述

Currently I'm scaling state values linearly from 1 to 1000, which seems unnecessarily arbitrary. A linear scale of 0 to 1 doesn't work either, but in theory it should because the area scaling is linear.

研究方向
The issue is in the file index.html at lines 329-332 where state values are scaled linearly from 1 to 1000. The contributor should analyze why a linear scale from 0 to 1 does not work as expected and identify the correct scaling function. Additionally, examine the d3.scale.linear documentation and the cartogram algorithm to determine the appropriate range and domain for the area scaling.
