link dynamic data to vis 2

large issues:
normalization of the data
sliding forward to max then back to min does not redraw over past
squares
updated normalization

added function using n/(average of 3 maxes). this value is then used as
the w,h of squares multiplied by a scalar.

needs redraw of white background between slider pulls
needs testing of sliding back and forth
normalized update

normalization is now dividing each category by the average of the top 3
maxes. this creates proportionality in each category, but does not
reflect population size across the six categories.

filtering on the highest 50% of pop distorts square visualizations.

the findMax function is not returning correct output***
URGENT FIX
reverse color scheme+moved labels to above squares

we also need to redraw the white background on each slider move
fix max possibly
