When visualizing, on a map, tens of thousands or millions of points in a dataset, data points may be spread all around the world, or be confined to a single country, region, city, or even some smaller area. In any case, there will be a zoom level in which the whole dataset is represented in a single 256x256 pixel tile. The “great mother of all tiles”, tile 0/0/0, will inevitably have to show the whole collection of points.
