You need a screen big enough to see our maps so
If (AND ONLY IF) the map is truncated in the very first screen you can

• Turn you web page fullscreen (F11 on Windows, ctrl+cmd+F on mac)
• Check your MS Windows resolution zoom to 100% (Windows parameters->System->Display)

• Check you web browser is not zoomed in
• On Safari: Click “View” then “Actual Size”
• On Firefox: Click “View”, then “Zoom”, then “Reset”
• On Chorme: Click “View”, then “Actual Size”
• On Edge: click - or + in Zoom menu

In any case you must reload this page and restart the experiment from scratch after any modification.
