StarPlot is a GTK-based program, written in C++, which can be used interactively to view three-dimensional perspective charts of stars. Charts can be recentered, rotated, or zoomed in or out with a mouse click (this can also, of course, be done via dialog boxes for more precision). Stars may be viewed (or ignored) by spectral class and absolute magnitude. Other features include support for both celestial and galactic coordinate systems, the ability to display extended non-stellar objects, and a pop-up Hertzsprung-Russell diagram. StarPlot is also packaged with starconvert, a utility which converts line-oriented stellar data records to StarPlot format. Most star data files available on the Internet can be converted this way if a short file describing the original file format is provided to starconvert.
