Graph Data Visualization

A tip of Data Importing (Windows Local File)

1. Start Neo4j

2. Create a new project folder

3. Open the http://localhost:7474/browser/

4. Create the ‘import’ folder under the new project folder Documents\Neo4j\New_Folder\import

5. Copy the CSV file at the ‘import’ folder

6. Import dataset using LOAD CSVLOAD CSV with Headers from "file:///city.csv" AS cityCREATE (ct:city {name: city.city, state: city.state, city_state: city.city_state, lat: city.lat, lng: city.lng, population: city.pop});

Spherical distance using the haversin function

CREATE (a:City { lat: 52.5, lon: 13.4 }),(b:City { lat: 37.5, lon: -122.3 })

RETURN 2 * 6371 * asin(sqrt(haversin(radians(b.lat - a.lat))+ cos(radians(b.lat))* cos(radians(a.lat))* haversin(radians(b.lon - a.lon)))) AS dist
