Margin renders some buildings invisible

[RomanenkoVladimir]

Bug

Due to D3's algorithm using margins between buildings removes small buildings entirely as they are not calculated, furthermore sizes are not correct, e.g. a buildings of size 400 is not 4 times larger then a building of size 100.

Expected Behavior

All buildings are calculated and placed on the map

A CodeCharta map with small buildings
WHEN
the map is visualized
THEN
all buildings are displayed with correct sizes

Actual Behavior

sizes are incorrect and some are not displayed at all

Specifications

• is released in online-demo: yes

Sorry wrong PR

I think the issue might be a result of using Math.cell() to often, please take a look and remove all intermediate usage by only applying it in the end instead :)
