Stateless Path drawing based on incoming data

Hi Friends,

I was recently working on one assignment where in we need to draw the flow of inventory movements based on the incoming data from the database. These datasets have to configured based on the routes coming from the database. Also, the case is values coming from database are redundant as well, so the algorithm has to be smart enough to figureout which route has been drawn and if same is getting repeated, then skip that part for the next time.

For making the same i have used one open API by google (, then modified the built in api based on my requirement. It’s a fairly, good combination of server side and client side projection. Below, is the sample code which i have used for the same.


Happy Coding
