Use cases for filter / blend-modes

filter allows a lot of things. The first idea stepping in my mind is using grayscale() function on other parts when hovering a chart, to improve the overall contrast between highlighted part and the others.

Other ideas:

• for alternate color schemes (inverted, dark or light, forced colors, high contrast…) with hue-rotate(), grayscale(), contrast(), etc.
• to alter a column — like the Pen I did for @GoOz
