#Range Area Graph This graph shows temperature ranges for each day in May.
The low temperatures are drawn as a clipping path to hide the bottom of the low temperature area. This allows for the use of gradients or photos or whatever you'd like in the background.
The graphs are also generated by a function, so the code is easily reusable. The low temperature graph is drawn with the opposite domain it would usually have: this makes it overlap with the high temperature graph to create a proper clipping path.
