How to find a Line on the map

Imagine you can not locate a line on your map, e.g. you created a very short line or even 1 dot by mistake.

• select the dataset entry in the SQL screen e.g. select * from radlvorrangnetz where cartodb_id=3598
• export to geojson
• go to a map e.g. "Spielwiese zum testen" (Sandbox map)
• add new Layer choose new dataset from geojson and browse to the exported geojson file
• edit the Style, choose a big line and activate the Label

Now you should see the lost line, even if it is just 1 dot.
