importing CSV data: please improve and explain

[Isee...]

PB: Importing is not straightforward and is not clearly explained.

Apparently:
1 you need two CSV files: nodes, and edges
2 the nodes file should contain ID and Label,, and possibly Modularity class (?)
3 then you must build an edge file, where you use ID, source, target, edgelabel. It does not contain the nodelabels (Myriel, Napoleon), but only "A", "B"... It is hard to build and illegible for maintenance !


Suggestions:
allow a single table (Graphviz DOTfiles allow this). On could perfectly leave some cells blank
or at least
allow mentioning nonambiguous nodenames (Myriel, Napoleon) in the edge table

Hi,

Thanks for your comments.

For nodes, you just need an id. Here is an example for a network of nodes Myriel and Napoleon:
id
Myriel
Napoleon

For edges, you just need "source" and "target", which take the nodes ids for values. Example:

source,target
Myriel,Napoleon

That's it.

If you want more complicated things (edge ids, labels, weights, directed or undirected edges, etc.) this is possible as well:

Imagine a network of Myriel and Napoleon, weighted, undirected, with edge ids and node attributes:

for nodes:
id,label,gender
a,Myriel,male
b,Napoleon,male

for edges:
id,source,target,weight,label,type
1,a,b,0.8,edge_1,undirected

Note that I used commas in these examples, but that Gephi allows for semicolons, tabs and spaces as well.

I hope this clarifies.

Best,

Clement
