Excel to Line thickness/typology

I have a large excel number set that i'd like help assigning relative line thickness to at different directions. For example, at 10 north would be thicker than 5 East, 3 South, 7 West, etc. I took the spreadsheet reader to extrapolate the data, then sort and partitioned to make a relative range of data. From there, I was looking to assign line thickness and typology and a direction, but I'm a little stuck. Any help would be appreciated. If there's any other way you think would be better, I'm all ears. Thanks
