The following map shows the spatial distribution of the dataset according to the provided tessellation.
Records outside the tessellation are indicated as number of outliers below the map.
The legend below shows the number of visits per tile ranging from 0 to the maximum number of visits per tile.
The allocated privacy budget for this map is shown below and noise is applied accordingly onto the counts.
The confidence interval is indicated below.
Tiles below a certain threshold are grayed out: Due to the applied noise, tiles with a low visit count are likely to contain a high percentage of noise.
For usability reasons, such unrealistic values are grayed out.
More specifically: The threshold is set so that values for tiles with a 5% chance (or higher) of deviating more than 20 percentage points from the estimated value are not shown.
