问题 Hi im trying to add some restaurants to an importet .osm file. So I want to save the restaurants as new Point Geometries and connect them at the right point with the existing osm graph. Later I want to read out all resturants and find the nearest restaurant from any given point. So should I add the restaurants in a new layer? And is there an easy way to connect the restaurants with the graph at the right geogaphical point?? Thanks for answers Greetings 回答1: There are two options: Edit the

问题 I'm new to neo4j. I have a .csv file with two columns separated by ",". The first column contains first names and the 2nd column contains the last names: Lname,Fname Brown,Helen Right,Eliza Green,Helen Pink,Kate Yellow,Helen I want to create nodes for Lname column and nodes for Fname column. For the rows that have the same Fname, I want to connect Lname to the corresponding Fname. For example I want to have a "Helen" node that three nodes "Brown", "Green" and "Yellow" connected to "Helen". I

问题 I like those example graphs mentioned in Neo4j's blogs and the Neo4j tutorial book. However, I can't find one tool that can draw the graph in modeling stage. The Neo4j Browser doesn't seem to be a good tool to do that. I would appreciate a lot if there is some recommendation on this. One graph example is here: https://neo4j.com/blog/data-modeling-pitfalls/ Those graphs look good. What tool can draw it? 回答1: I think those are hand-drawn. My go to tool is still arrows, which works really well

问题 I am using JSON APOC plugin to create nodes from a JSON with lists in it, and I am trying to create nodes whose label is listed as an element in the list: { "pdf":[ { "docID": "docid1", "docLink": "/examplelink.pdf", "docType": "PDF" } ], "jpeg":[ { "docID": "docid20", "docLink": "/examplelink20.pdf", "docType": "JPEG" } ], ...,} And I want to both iterate through the doctypes (pdf, jpeg) and set the label as the docType property in the list. Right now I have to do separate blocks for each
