How to implement google charts customization to the following view?

Answer 1

If the "elegance" of the solution suits you, then you can try by pulling out the coordinates from the finished SVG and placing a translucent object from the series under it
Much easier with custom tooltip - there you can create a custom column and use the isHtml option to drive beautifully styled css content
