d3.js - Best and optimized way to crate web based Interactive Choropleth Map -


i going build interactive choropleth map bangladesh. goal of project build map system , populate different type of data. read documentations of openlayers, leaflet , d3. need advice find right path. solution must optimized enough.

the map going create following http://nasirkhan.github.io/bangladesh-gis/asset/base_files/bd_admin_3.html. prepared based on leaflet js. not mandatory work library. tried leaflet because easy use , found expected solution within short time.

the requirement of project prepare choropleth map can display related data. example have show population of divisions of bangladesh. @ same time there should options can show literacy rate, male-female ratio , on.

the solution working have issues. load time huge , if want load 2nd dataset have load same huge geolocation data, how can optimize or avoid situation?

leaflet has layers control feature. if cut down data required, split different layers , allow user select layers interested in viewing might cut down on loading of data. option simplify shape of polygons.
