Currently I am lucky because I have some time to create vizzes with Tableau 10. I am very curious about Device Designer efficiency and use. That is why I did a couple weeks ago a viz about french wine. This week, I used Open Data about subway in Paris (again!). Since my first wiz about Paris' subway, I want to show visualisation about time and trip. that is why I chose GTFS files (all data are available here : GTFS files).
