Maybe this can help ? the Figure 1 shows some results similar to your needs ? http://www4.fe.uc.pt/spatial/doc/lecture2.pdf

Please note, when I use google API I do save the results as very high resolution image, which are good enough for scientific publication.

You should refer to some Geo Science toolboxes, like this one.

Also this kind of visualization is trivial in D3.js. So you may also output the data into a json or so and plot it with D3.js.
