Possible min threshold for osm data points

[jstrahler]

When trying to display osm data, small data sets do not display on bridges

Note: change user and id to whatever yours is
failure case command: ./osm 5 jstrahler 209382050691 35.2971 -80.7475 35.3162 -80.7211

success case command: ./osm 6 jstrahler 209382050691 35.1971 -80.8475 35.3162 -80.7211

Jay, this is a binary.. can you provide the source code for this so I can test?

Ok, for very small graphs (right now set at 2000 nodes), you need to make the following call for OSM data:
graph.setLargeVisualization(true);

This forces it to render using webgl. Force directed rendering is not supported for OSM graphs, I believe.

Oh, I tested it with this additional call and it works fine.

Note that I don't know really why the regular visualization does not work for these grpahs. Should we include the graph.setvisualization(true) inside the function that build the graph from data? Erik
