The spectra for each element is computed and plotted in your browser by a Java program which reads a file containing a list of emission line wavelengths and their corresponding strengths.
This program generates deep 24 bit color plots, therefore you may need to increase the color depth of your system to view subtle details in these spectra.
The element, wavelength range and line width are all controlled by applet parameter tags in the HTML source for this page. There are other options such as width and height of spectra in pixels and contrast which can also be controlled. There is also an option to overlay a white blackbody continuum of varying strength.
