Is that the 'halo' in the lighter shade in each square?
Yes! Also hold down "p" to see a production heatmap.
Thanks! Are the yellow squares the highest production in the heatmap?
Yep. Also, if you click on a square and hold down the click, the strength and production of that square will appear in the top right of the visualizer.
What's the relationship between starting strength & production?
Believe there is none. They are both generated with a similar/same algorithm though.
That's correct - they use the same algorithm but are independent.
