- - - - ACRE SIZE COMPARISON - - - -

Nice graph.  When you get the time, would it be possible to add the unit of the "perch" (sq. rod) to the chart?  As the acre is defined as 4x40 of these originally, it is a more important unit than the square chain to have a comparison.

Also, the rood, quarter acre is also used for subdivisions that don't simply decimalize acres for sale.  In Sri Lanka, Jamaica, and at one time in all countries that used acres for land, deed descriptions were broken down ACRE, ROOD, PERCH.

In any case, this is a great visualization.  Thanks for adding it!
