d3 example graph search - description query

This iteration add an interaction that opens the block represented by a node when you click on that node

In this iteration, we load json data from a static file. This json data is produced by the REST API of a neo4j graph database that contains the d3 example README citation graph, in response to a query that we post to it.

This query finds all blocks that have the string map somewhere in the description (gist title) show those blocks and all blocks that they have a 1st degree link-in-the-README citation relationship with

MATCH(n)-[:LINKS_TO]-(m)
WHERE n.description =~  '.*map.*'
RETURN n, m

the cool thing about this is the related nodes may not have map anywhere in the description, but we can still use some known graph of d3 example relationships (in this case README citations) to infer that they are relevant to a map keyword search
