Hello,
the instruccion to pack a custom visualization like sankey, donuts, etc are too complex and cannot be followed on every single computer arround the network, since for each implementation there is local things that also need to be done (like installing custom R packages or padoc).
Please provide us with .spk or .sdn files to use/implement those new visualizations and easy ways to pack padoc or custom R packages for example to those packages.
As of Spotfire 11.0, the core product now features visualization mods that overlaps to a large degree with JSViz. More on this here:
