I need to create a map with the Import and Export Flux between countries. I have the needed data in my table. But I wish to know if there is any tool or extension which will allow me to create those lines or arrows automatically (similar to how we do with labels, but those create words, which organize themselves in the Data Frame).

For that all I should do is to indicate lineament of origin and destination, representing the seaports.

I need to do something like this, but with arrows:

There is a distributive flow tool available in the applications prototype lab.
Here is a blog and some links and data.
Even if you are not looking for this.
I like it so here.

With your edit addition to the question I will add this link for placing line decorations with code.
If you desire more help on using arrows add to your question and I can provide some detail.

  • Fantastic! This is quite elegant. – NaN Sep 11 '13 at 14:08

    This tool is very interesting, but I need to represent direct flows. In the figure above flows are mixed in the way. – Fernando Alves Sep 11 '13 at 15:48
  • I have not been through the exercise provided but I think they are all single lines that offset parallel when they are coincident in origin or destination. The example shows 1 destination. perhaps with multiple destination you would get the results you are looking for. Also you can use line decorations to create arrows (however not sure how it would work with this solution). – Brad Nesom Sep 11 '13 at 19:18

I think what you want could be found in this Esri blog post called Creating radial flow maps with ArcGIS
