prep.html

Webpage with JavaScript that reads in the other data files to prepare a data set for the visualization app. The file loops over the requested forums, copies over node x,y coordinates as provided from the GDF files. Finally, the system computes and saves betweenness centrality scores for all nodes. All variables are written out as simple arrays. Both node and edge data are stored on a top-level object on a per-forum basis.

Edges are determined from the post data in ohcg.js. This appears to be inconsistent with edges listed in GDF files.

The text generated by this webpage should then be saved as the file "ohc.js" in the parent directory.
