Hi Nadeem, what do you mean with 'underlaying graph structure' the actual size, structure or the database, please tell us what you want to archieve.

OSM data consists of three basic types, called elements. These are nodes, ways and relations. Each of these elements can have additional tags in order to describe them.

There are various ways of downloading OSM data. The Planet contains all of these elements with all their tags for the whole wold and consequently it is very large. There are also extracts for continents and countries available. For even smaller areas you can either use the API directly or with the help of an editor like JOSM which is probably easier.

Then there is also the possibility of filtering data to reduce its size and strip unneeded elements or tags. You can filter the data before downloading it by using the Overpass API. And you can filter the data after downloading by using osmfilter / osmconvert.
