Lists all available India map layers — boundaries AND data layers.

Lists all state and union territory names available in a given map boundary set.

Lists all districts available in a given district-level map boundary set.

Renders a choropleth map of India at the state level.

Renders a choropleth map of India at the district or sub-district level.

Returns a CSV template for a given map boundary set.

Lists all available showcase demo datasets (NFHS-5 health indicators and IHME AMR estimates).

Generates a shareable BharatViz URL for a given demo dataset.

Lists all 38 Indian states and union territories that have pincode boundary data.

Resolve a single pincode to its centroid coordinates plus the district and state it falls in.

Lists pincodes (postal codes) for a given Indian state, district, or all of India.

Renders a pincode-level choropleth map of India.

Lists all available Indian cities with ward/zone boundary data.

Lists all ward names for a given city.

Renders a ward-level choropleth map for an Indian city.

Point-in-polygon lookup: given a latitude and longitude, returns the containing administrative unit(s) from one or more BharatViz map layers.

Filter and aggregate features in any registered BharatViz map layer.

Spatial join: find all features from a TARGET layer that fall inside a boundary selected from a BOUNDARY layer.

Find features within a given radius (km) of a center point, across one or more map layers.

Centroid (lat/lon) of any feature in any layer — district, state, constituency, ward, pincode, point, or polygon.

Compute area in km² for one or more features in a polygon map layer.

Returns the raw data download URL(s) for any registered BharatViz map layer.

Traces how a district's administrative boundaries evolved across Census years (1951-2011).

Lists all district names that appear in the Census transition data (1951-2011).

Describes the schema of any registered BharatViz map layer: which columns are numeric (with min/max/mean), which are categorical (with unique-value count and sample), and which are free-text identifiers.

Compute descriptive statistics (count, min, max, mean, median, p10, p25, p75, p90, stddev, sum) for one or more numeric columns in any registered map layer.

Sort features in any map layer by a numeric column and return the top or bottom N.

Compute Pearson and Spearman correlation between two numeric columns across features.

Compare named groups of features side-by-side on numeric columns.

Find the K features most similar to a reference feature using Z-score normalized Euclidean distance across a multi-column metric vector.

Count (and optionally sum/mean/min/max) target-layer features inside each boundary polygon.

Bulk nearest-distance + within-radius coverage: for EACH source feature, returns the nearest target feature, its distance (km), whether it is within radiusKm, and how many targets fall within radiusKm (a density metric).

Join numeric columns from two map layers by matching feature names.

Describes the schema (columns, types, ranges) of a city ward dataset.

Compute descriptive statistics for numeric columns in a city ward dataset.

Sort ward features in a city dataset by a numeric column and return the top or bottom N.

Lists all available BharatViz map layers grouped by category.
