Spider Diagram Tool for ArcMap

Spider lines depict Euclidean distance-based routes that connect each pair of points. They are a useful tool for visualization. In landscape genetics this represents the isolation-by-distance hypothesis. Previously there were other 3rd party tools that achieved this on the Arcscripts website. Currently it appears that this functionality is only available with a Business Analyst license of ArcGIS. This tool make a few assumptions: 1. You wish to connect all pairs of points.2. You have a point shapefile.3. The point shapefile is in a projected coordinate system.4. The point shapefile has fields called "Easting" and "Northing" that represent the X and Y coordinates respectively. If these fields are not named this excatly then the tool will fail.5. You have a field that describes the name of the pairs of the site (point). Please do not use a geodatabase feature class.
