Description
Neo4j 3.4 delivered some powerful new spatial and temporal features for modeling and querying graphs that include location and date-time elements. In this talk we will show you how these capabilities can be used to build web application with interactive maps that allow intuitive querying of spatial and temporal graphs. To really turbo-charge your application we'll show you how to import data from the single biggest spatial graph ever, the OpenStreetMap graph, as well as how to extend the capabilities of Neo4j from mere point locations to polygon searches.

generally useful for many things, we used it for batching the imports https://github.com/neo4j-contrib/neo4j-apoc-procedures

My recent discovery of (and subsequent crush on) the d3.js library is what had me sign up for Online Meetup: Neo4j Spatial. Any suggestions for a first things first approach to data modeling/visualization from more seasoned developers’ perspective with hindsight (as per ”if I could learn what I know now, again - I’d start with ‘xyz’ ”) would be greatly appreciated. Also curious of this event will be recorded/available for viewing following it’s scheduled duration.

Thanks so much. - @taytbicknell

Hi @taytbicknell, I think it's best to ask questions about visualization and graph app development as new questions in the categories #neo4j-graph-platform:visualization or #neo4j-graph-platform:graph-apps. I used react here only because Will Lyon used react to build the original. If I were to build another from scratch, I'd likely use react but only because I have some familiarity with it.

Used a number of different javascript frameworks - definitely react is the way to go for geospatial visualizations. There is a lot of routing/state management involved once you get past the simple map aspect in making an interactive spatial->text->graph search/visualization UX. We originally did our dataLink platform using angular, and ended up having to re-write in react as the routing/state management became a nightmare... React solves much of that, although there is certainly a learning curve..
