+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 are numpy and scipy (to improve python scripting)

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
