Maps Visualization

The scale matters as much as the shape.

A filled series emphasizes magnitude above a zero baseline.

Data source: World Bank WDI / ADG local snapshot

Method: Area is not an accumulated count over time. Each point is a population stock.

Maps Visualization

One hundred units. One selected total.

Parts divide one non-overlapping total. The data table retains exact values.

Data source: World Bank WDI / ADG local snapshot

Method: Grid cells are rounded percentage shares.

Maps Visualization

Read across time. Then across countries.

Rows are countries, columns are years. Each cell retains its measured rate.

Data source: World Bank WDI / ADG local snapshot

Method: Color shows magnitude, not statistical significance.

Maps Visualization

How often do rates fall in each interval?

Bar height is a count of observations in a numeric interval.

Data source: World Bank WDI / ADG local snapshot

Method: Bins affect the appearance. These country-years are not independent survey samples.

Maps Visualization

How concentrated is this selected population?

Bars show shares; the line accumulates those shares to 100%.

Data source: World Bank WDI / ADG local snapshot

Method: The denominator includes only these six countries, not all West Africa.

Maps Visualization

Use area to show parts of a whole.

Parts divide one non-overlapping total. The data table retains exact values.

Data source: World Bank WDI / ADG local snapshot

Method: Small differences are easier to compare with bars.

Maps Visualization

Four histories, one set of axes.

Trace each series through time. The vertical position is an annual rate.

Data source: World Bank WDI / ADG local snapshot

Method: Annual observations do not reveal within-year volatility. No smoothing is applied.

Maps Visualization

Equal tiles, different economies.

One tile represents one country. Equal tiles remove land-area dominance.

Data source: World Bank WDI / ADG local snapshot

Method: Distances and boundaries are schematic. Use the geographic maps for location.

Maps Visualization

A third variable, carried by area.

Each point is a country. Bubble area represents population.

Data source: World Bank WDI / ADG local snapshot

Method: No trend or causal model is fitted. Nominal GDP is not purchasing-power parity.

Maps Visualization

Track the distance between two years.

Each pair links the same country. Position gives the rate in each year.

Data source: World Bank WDI / ADG local snapshot

Method: The line does not describe the path between the two observations.
