Help with creating a map of links

[rajesh]

Hi mapping gurus,

I would like some help with creating a map showing links. I have a list of hundreds of pairs of points.

I am a completely beginner and started with Gephi, but the map with Gephi does not want to wrap itself neatly onto the plotted points.  I can generate the plot without the map.  And there does seem to be a way to line the two up within Gephi, either.

I quickly browsed some of the material in this forum: https://github.com/geohacker/data-and-maps - apologies for asking without deep searching and playing with options.

Can someone point me to something? My dream is to make something like this: https://www.facebook.com/notes/facebook-engineering/visualizing-friendships/469716398919

Thanks in advance,
Rajesh

Hi Rajesh,
What software and data do you have?
Sometime back, I created the following map using Qgis and PostGres/PostGIS:

Do you want to create something like this?

The difficulty of the process depends on the data that you have, and how much you need to massage it, to create the curved lines. Once you achieve that, then making the Map in Qgis is a very small task.

Hi Devdatta,

We have a MySQL database out of which we exported to csv, then through VBA to transform to xml.
We are using Gephi for plotting the points. The map option in Gephi is giving us a wierd offset and we don't have (or see) all the options to do stuff like the below.

Thanks,
Rajesh
