My first steps in Gephi: Need Help - Can't get meaningful result

[Enomine88]

Hi,
a) downloaded Gephi 0.10.1.
b) Saw that it supports CSV-Format: https://gephi.org/users/supported-graph-formats/csv-format/
c) Put the data into a matrix:
I) original
Freelancer_Matrix_Beziehungen_fuer_Gephi_original.csv
d) loaded this CSV. On import he warns about negative weights.
e) Under "Layout" i choose "Fruchterman Reingold" and pushed "start". Tried different speed (1, 10, 100)
f) Nothing meaningful happens. The graph does just dither / shake / quiver / jitter (don't know what is the best translation of german "zittern").
g) Tried no negative weights by adding 0.5 to every weight:
II) No negative weights (added 0.5 to every)
Freelancer_Matrix_Beziehungen_fuer_Gephi_no_negative.csv
h) Nothing meaningful happens.
i) Tried no weights under 1 by multipliing with 10 to every weight:
III) No weights under 1 (multiplied 10)
Freelancer_Matrix_Beziehungen_fuer_Gephi_no_negative_and_times_10.csv
j) Nothing meaningful happens.

Could anyone help me doing my first steps?

Thanks - Enomine

Just to be clear this is what i expect (Screenshot from a youtube-video):

Here we see school-classes 1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b, 5a and 5b. All clustered and painted in color.
The notes do not form a geometrical form - they order themselve into clusters we can distinguish from each other.

Thanks - Enomine

I haven't tried importing an adjacency matrix into Gephi, but assuming this data is structured correctly, this screenshot is using the Force Atlas 2 layout, which first tries to pull nodes into communities (the clusters you see), then pushes those communities apart as much as the connections between communities allow. Fruchterman Reingold often returns that filled-in circle layout for networks with networks that are densely interconnected, since it's not trying to push communities further apart.

Mathieu Jacomy's Gephi tutorials are really helpful.
