About this map

The map below shows a few major Indian cities with popups, clustered markers, and an optional heat of circle markers just for fun. Use the layer control (top-right) to switch basemaps and toggle overlays.

# Sample points (feel free to personalize!)
cities <- tibble::tribble(
  ~city,       ~lat,     ~lng,    ~group,
  "Mumbai",    19.0760,  72.8777, "West",
  "Delhi",     28.6139,  77.2090, "North",
  "Bengaluru", 12.9716,  77.5946, "South",
  "Kolkata",   22.5726,  88.3639, "East",
  "Chennai",   13.0827,  80.2707, "South",
  "Hyderabad", 17.3850,  78.4867, "South",
  "Pune",      18.5204,  73.8567, "West",
  "Ahmedabad", 23.0225,  72.5714, "West"
) %>%
  mutate(popup = paste0(
    "<b>", city, "</b><br/>",
    "Group: ", group, "<br/>",
    "Lat/Lng: ", round(lat, 4), ", ", round(lng, 4)
  ))

# A simple polygon (approx bounding box around India for decoration)
poly_latlng <- list(
  rbind(c(8.0, 68.0), c(8.0, 98.0), c(37.0, 98.0), c(37.0, 68.0), c(8.0, 68.0))
)
