This is how to access the data at SkyServer and some work around for rough spots. It starts here at the SQL entry form. The automation of the process is a second level of integration and is accomplished with a python web interface as well as glue to hold it all together and perform the graphing using python graphing libraries as well as PyOpenGL. This page has examples of SDSS queries, which are copy and pasted into the entry form as linked and click on submit to see results.
The image is from kstars focused on Betelgeuse , which is an interesting giant star that varies quite a bit and perhaps has already exploded and we just don't know it. I personally find it to be one of the most interesting objects and easily located in the winter sky, even near city lights.
