This feature allows the users to visualize the extent of MnROAD data that is available for a given category such as Study, Roadway, Structure, Traffic, and Performance monitoring. The available data is based on the selected filters and sections. For each category (piece of the pie), the blue color shows the ratio of test sections (as per the selected filters) that have available data in that category. On hover, the user will see the total test sections and the counts for that category. Whereas, in field monitoring categories, the user will see the test section counts on which monitoring is done and the corresponding minimum, average, and maximum number of field visits.
