Change color to lines of the profile progress graph

If you look at any profile https://lichess.org/@/Toscani Then drag the bottom date slider back to say 2013. You will notice that the colors are overlapping. They still over lap on a 27 inch screen and even when I zoom the browser to 140%. My proposal is change the 250 increment rating scale to 100's. The rating scale needs more height, so that the colors don't overlap. 2000 1750 1500 1250 1000 Have a slider also on the rating side of the graph, not just on the dates. It will help to zoom in and make things more distinguishable. If there was a selection button, then only the ones we wish to see, would be visible on the graph. Or the other lines could become lighter in color. Like highlighting the lines we want to see.
