not finished yet but functional: overwiew of amount of measurements by NUTS3 Region. (not linked to from main page yet, will be added once layout is finished / legend added etc.) indoorco2map.com/frequencymap.h…

Some small improvements to the Website: 1) Detailed view of Location now has max 5 entries per page and is sorted by date rather than random. 2) there is a Button in the top to zoom out to whole World 3) Activity Map (via Menu) also has a World map showing measurements by country

When hovering over an entry in the legend it now shows the additional info which was entered during recording. (For Windows and Venilation System, the client will be updated to not have "False" as default but "No Data", to distinguish better.
