<p>Greetings,<br>
<br>
We are hoping to promote VTK for mainstream use within our organization as a platform for information visualization of global issues. Noting the recent developments of Titan in the areas of geovis and infovis, we see great potential for applications in our typical analysis use cases. Our task is to create a set of "provenance" patterns for conventional representations such as choropleth map, 3d bubble plot, social network, etc. We are currently using VisTrails to create these "recipes" to enable our non-technical user-base to select among the examples. This is the idea, but here is the problem. It seems that detailed documentation and examples for the infovis/geovis packages could benefit from some "real-life" test cases. For example, here is the current scenario we are working with:<br>
<br>
a.) A world country border geometry provided as shapefile.<br>
b.) A CSV delimited file with Country ID (matching shapefile) and statistical information such as Population, GDP, etc.<br>
c.) A render of country polygons (based on SHP) where each country polygon is colored (choropleth) based on a statistical parameter.<br>
d.) A symbol marker (such as proportional cube) is placed on map based on statistical variable.<br>
<br>
We would be very grateful for this community's indulgence to brainstorm and elaborate the VTK implementation of such a case. We are hoping your inputs can provide some needed guidance (pseudo code) for us to assemble the needed VTK logic.<br>
<br>
If it would be useful, we would be happy to "give back" this work and provide detailed documentation for using VTK for these scenarios. In other words, we'd be happy to share what we learn by contributing instructional sources (wiki write-ups, etc.) for using VTK/Titan for common information visualization purposes.<br>
<br>
Thank you kindly for your support and advice.<br>
