Osm map imported to Arangodb

I am new to arangodb. I am going to use arangodb to perform algorithms on a road network.

I found this https://github.com/arangodb-helper/osm-2-graph?files=1

I tried to import the edges file, vertices file into arangodb using arangoimp (in json format).

But I could see only single node always. It doesn't get expand after clicking expand button. Full network view only shows nodes, no edges.

Could you give correct steps with commands ? Seems I have trapped somewhere.

I used Monaco osm map. Using arangodb 3.2 version

Edit 1 : my commands as follows

arangoimp --file V-CA.json --collection vertices --create-collection true --type json

created: 1896 warnings/errors: 0 updated/replaced: 0 ignored: 0

arangoimp --file E-CA.json --collection edges --create-collection true --type json --create-collection-type edge

created: 256 warnings/errors: 0 updated/replaced: 0 ignored: 0

OSM to graph file conversion

python convert-pbf.py monaco.osm

Edit 2

I observed same results after using 3.3.7

I saw it shows

250 nodes 0 0 edges

at he botton after "Load full graph". But at the import it shows 1896 vertices. Is it showing part of vertices only?

Are the document and edge collections looking alright? Can you get a graph result via the query editor in the web interface? (You need to return edges or paths in order to trigger this result display mode). Note that the graph viewer for named graphs shows a random start vertex and its neighborhood by default. You can change the start node, but not visualize the entire graph. – CodeManX
yes. I have updated the import commands. – user3478108
Can you try the latest version (currently ArangoDB 3.3.7) and add a screenshot of what you see in the web interface? – CodeManX
Ok . Please give me sometime – user3478108
Did same as previous. Please note I have updated the Questions with results – user3478108

The graph viewer has a default limit of 250 nodes. This can be adjusted in the properties panel (open it with a click on the hamburger icon) in the section Graph in the field Limit:

ArangoDB Graph Viewer Settings

Set it to 2000, hit return and load the full graph and wait a bit.
