Multicolored anchors

Anchors to the sub-maps should reflect the overlay of experimental data in their respective sub-maps. This should be done by creating a 'mosaic' visualisation of an anchor element, as shown in the picture. Most under-expressed and most over-expressed values should be illustrated per dataset.

Sub-sub-maps should not be considered, only directly linked sub-maps.

If another element is named exactly as the anchor, it should be colored exactly as the anchor.
