Do I have to use Views to use all the behaviors of OpenLayers maps module? I just started using the http://drupal.org/project/openlayers module. There are plenty of tutorials to learn about it, but all of them make use of views to show the maps.

I need to show a simple map to show a single the location. I need this map to show a marker and a tooltip with some information (address, phone,...) 

I tried showing a map in a node by adding the geofield field to a content type and then setting the OpenLayers Map Widget in manage display.

The map is shown up fine but as far as I see there no way to add a popup to the map.

Then my question is: Do I need to show the maps through a view to get all the behaviors provided by the module?
The learning curve is a little steep when first working with openlayers if you really want to use it you can create your map and add a geoJSON layer to it and just write the geoJSON code in the textarea provided to create the point and popup info. Checkout openlayers plus module for more behavior options.
