D3.js force directed graph (website link graph)

We require a skilled and experience D3.js developer to create a first draft/proof of concept tool that can render a a large website structure using a force directed graph. I can supply data for two test sites, site A = 8k nodes / 180k edges and site B = 700k nodes, 24M edges. Ideally, we are looking for an end result similar to those produced by [login to view URL], but crucially we need to figure out how to handle a typical website link pattern (eg. lots of links in and lots of links out of every page) which would normally result in very messy visuals. One train of thought is using Force Directed Edge Bundling (FDEB) [1] which could essentially hide weak links and surface strong links between pages. Your input here will be crucial. To help this process, our crawlers export two CSV files: - [login to view URL] (URL pairs showing link direction), example: ---------- pageA,PageB PageB,pageC ---------- - [login to view URL] (final PageRank distribution of nodes) ---------- pageA,1.12345 pageB,1.05678 ---------- From this data, you could also weight the edges based on the linking pages PageRank (eg. score / number of links). Additionally, it would be great if nodes/trees were collapsible [2]. [1] [login to view URL] [2] [login to view URL]
