Flatland Visualization Feedback
This questionnaire intends to collect feedback for Flatland Visualization which is a visualization tool to analyze train scheduling behavior in an episode of Flatland environment.

The latest version of the tool is available at: https://vis-tools.paluno.uni-due.de/fv/ 
The tool might have been updated since your last visit, so please remember to clear the browser cache, or open it in incognito mode. The tool works best in Google Chrome browser.

Please take a few minutes to explore the latest version. You can also watch a short video explaining the available features and interactions in the tool: https://uni-duisburg-essen.sciebo.de/s/0Y48FChe2zlBQQW.

The questionnaire will take about 35 minutes to complete.

The remainder of the questionnaire will ask your opinion on discovered insights on train movement behavior, individual components of the tool, the overall system followed by some questions on general issues. Please open the tool at https://vis-tools.paluno.uni-due.de/fv/ and familiarize yourself with it.
Train Movement Behavior
Please mention the name of selected episode (top-left dropdown) in your answer while describing the observed patterns in the visualization.
Please name the three insights you find most interesting (if possible). An insight might be any domain- or data-related fact that you have discovered using the visualization: *
