This is only a hello world example of ofxCV + ofxUI demo.The white lines show the motion direction, ofxUI provides the interface to control the video window. To compile the two addons together without errors, I actually downloaded two more addons, which are ofxOpenCV and ofXmlSetting.

It took a while for me to figure out how to scrape the data and how to use the mesh but after that it went pretty smoothy.
The hotels are plotted based on location with colors representing their rating. Green = well rated, Red = poorly rated, Blue = No rating given.
The user can zoom and rotate and can control what information is displayed on the Z-Axis.
[ENTER] – To view Price on Z-Axis
[SPACE] – To view Rating on Z-Axis
As would be expected we see that those which are more expensive have better ratings. Also amusingly it looks as if America has the worse rated hotels. However it seems like it may just be that far more hotels in the US reported ratings compared to other countries, so those in other countries may not typically report unless the rating is positive.
