Deep analytics
Beyond top-N bars — concentration economics, power laws, multi-dimensional comparisons and time flows.
Surname Concentration — Lorenz Curve
Cumulative surname share. Diagonal = perfect equality. The further from the diagonal, the more concentrated.
Pareto — 80/20 Castes
Bars (descending) + cumulative line. The red dashed line marks where 80% of records come from.
Zipf / Power-Law — Caste Rank vs Frequency
Log-log scatter. A straight line means caste distribution obeys a power law (like word frequencies in language).
District Profile — Radar
Top 8 districts on 5 normalized dimensions: records, caste diversity, gotras, villages, gender balance.
District Records over Time — Stream
Stacked stream graph (centered baseline) of records per year, split by top 6 districts.
District ↔ Caste Chord Diagram
Ribbons connect top districts to top castes — width = record volume of that combination.
Marimekko — District × Caste
Variable-width stacked bars: row height ∝ district size, column width ∝ caste share within that district.
Family-Size Beeswarm
Each dot is one family, vertical jitter prevents overlap. Position shows size on a log scale.
Bahi Atlas
