[Feature Request] Restructure timeline when displaying more than a month of data

[dgraf-gh]

At the moment selecting more than a month of data leads to a convoluted timeline since we only display them in a straight list how the visits have happened. This gets overwhelming and does not provide any meaning when displaying larger time ranges.

Here we want to come up with a new ui for this mode and further reduce the load time when selecting a large time range.
