starplot binary package in Ubuntu Focal amd64

 StarPlot is a GTK+ based program that can be used interactively to view
 three-dimensional perspective charts of stars. Charts can be re-centered,
 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.
 .
 StarPlot is packaged with starconvert, a utility that 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.
