Interactive epidemiological spot maps for India

SpotMap

Interactive epidemiological spot maps for India

SpotMap turns a CSV of case/control coordinates into a publication-ready interactive HTML map with:

• Dot density clustering (cases only)
• Spot map pins (cases and/or controls) with custom colours
• Automatic state/district boundary overlays (bundled data — no shapefile setup needed)
• Sidebar with mode toggle, colour pickers, pin size slider, and PNG/PDF export
• Smart auto-detection of latitude, longitude, and outcome columns

---

Installation

pip install spotmap

---

Quick start

Python API

from spotmap import SpotMap

SpotMap("my_data.csv").build().save("map.html")

Command line

spotmap my_data.csv -o map.html

---

CSV format

SpotMap auto-detects columns — no strict naming required.

Requirement	Details
Coordinates	Separate lat / lon columns or a combined "lat,lon" column
Outcome	A column named outcome, status, case_control, etc. with values like case / control

Example:

latitude,longitude,outcome
28.6,77.2,case
19.0,72.8,control
13.0,80.2,case

Python API reference

SpotMap(
    csv_path,                       # required
    state_shp=None,                 # custom state boundary (shapefile/GeoPackage)
    district_shp=None,              # custom district boundary
    lat_col=None,                   # override auto-detection
    lon_col=None,
    outcome_col=None,
    case_value=None,                # value that means "case" in outcome_col
    count_cutoff=2,                 # districts ≤ cutoff → district zoom
    margin_deg=1.0,                 # boundary crop padding
    cluster_color="#E85252",        # dot-density bubble colour
    case_color="#D55757",           # case pin colour
    control_color="#7676E7",        # control pin colour
)

Chain calls:

sm = SpotMap("data.csv", case_color="#FF0000").build()
sm.save("map.html")

# Access the raw Folium map for further customisation
folium_map = sm.map
