SciDAVis (data analysis and visualization)

SciDAVis is a free interactive application aimed at data analysis and
publication-quality plotting. It combines a shallow learning curve and
an intuitive, easy-to-use graphical user interface with powerful
features such as scriptability and extensibility.

SciDAVis started as a fork of QtiPlot.

Optional dependencies, after installation, are scipy and pygsl (to
improve python scripting).

Note:
I have a #TODO in scidavis.SlackBuild: to avoid using qwtplot3d (qt5
version) installed in the system
