Coursera - Developing Data Products - Week 2 Peer-graded Assignment

Overview

The goal of this project is to create a web page using R Markdown that features a map created with Leaflet. I have hosted my webpage on RPubs.

Summary

I have picked up an open source data for India’s population as per 2011 census and plotted all its states.

setwd("~/Coursera/Developing Data Products") # Set working directory
India_map <- read.csv("state wise centroids_2011.csv", stringsAsFactors=FALSE)

Plotting Data

myMap <- India_map %>% 
  leaflet() %>%
  addTiles() %>%
  addMarkers(lat = India_map$Latitude , lng = India_map$Longitude, clusterOptions = markerClusterOptions(), 
             popup = paste("Region:", India_map$State, "<br>",
                           "Population (million):", India_map$Population_million,"<br>"))
myMap
