5. VOPlot 2D: Features contd.
Supports basic statistical analysis: several uni-variate and multivariate functions supported.
Column transformations based on expression.
Data subset creation based on filter condition.
Inter-operable with Aladin developed by CDS.
This enables simultaneous visualization of some graph in VOPlot together with a representation as a sky plot in Aladin.
Projection maps for Sinusoidal, Aitoff and Mollweide Projections.

12. VOPlot 3D - Introduction
Motivation: Web-based visualization of data in VOTable format in 3D.
Should be interactive – operations on graph such as rotations, translation, zooming should be easily possible.
Should support user interface similar to 2D VOPlot.
Should support features already existing in 2D VOPlot.
