A heat map shows a set of data in a grid in line with other vectors of data. You will need to define an array of hashtables. One axis will be the property to index by while the other vector will be a set of keys as defined by other properties of the hash table.
$Data = @(
@{
state = "idaho"
cats = 72307
dogs = 23429
moose = 23423
bears = 784
}
@{
state = "wisconsin"
cats = 2343342
dogs = 3453623
moose = 1
bears = 23423
}
@{
state = "montana"
cats = 9234
dogs = 3973457
moose = 23472
bears = 347303
}
