Deck.gl 3D Column Bars
3D cylindrical columns standing up out of the basemap — every column sits at a geographic point and its height encodes the metric (population, sales, footfall, sensor reading). Deck.gl's ColumnLayer renders n-sided prisms (16 sides by default for a smooth cylinder) on the GPU wit

When to use this template
This visualization makes it obvious how a single quantitative metric varies across many distinct geographic locations. An analyst reaches for it to quickly identify spatial patterns, outliers, or clusters of high/low values at specific, predefined points on a map, leveraging intuitive height encoding for quantitative comparison.
- Data with precise geographic coordinates (latitude, longitude) for each record.
- A single quantitative metric to be visualized as column height.
- Discrete, named locations rather than aggregated areas.
- Comparing relative magnitudes across many distinct points.
- Individual point values are important, not just density.
- Benefits from 3D perspective for understanding spatial relationships.
