When you need to convey where availability zones are located and how they change over time, a map is the most effective visualization. A map lets you plot each zone at its real geographic location, making spatial relationships, clusters, and gaps immediately clear. You can layer past data and forecast data on the same geographic canvas, using different colors, fills, or line styles to distinguish historical years from projected ones. A time slider or animation can reveal how the set of zones evolves over the last decade and into the next five years, which is exactly what you need for both retrospective view and forward planning.

Bar charts, mosaic plots, and pie charts aren’t suited to this task. Bar charts focus on values over time or categories but lose location context, which is essential for zoning. Mosaic plots and pie charts handle proportions of categories but don’t convey geographic placement or growth across years, making them poor choices for illustrating where zones exist and how they’ll expand.
