Loading zones from GeoJSON...
CSV file must be an NxN matrix, where N is the number of zones in the selected geojson.
Each i-th line contains the N probabilities of a marker that start from the i-th zone and goes to other zones.
The sum of all values should be 1.
Example with two zones:
0.10,0.30
0.45,0.15
10% of markers will go from zone 0 to zone 0
30% of markers will go from zone 0 to zone 1
