Prerequisites

Nokia Maps API supported web browser (basically any modern web browser)

Important about Maps credentials

From version 2.2 of the Nokia Maps API onwards, authentication credentials are required to use the Nokia Maps API servcies. If you start without having any credentials, a map may not be displayed. In order to get the full potential out of the offering, you must get the credentials that authenticate your application against the Services. Please read through the Location API. For more information on how to obtain the credentials, please start with the Nokia Maps API Developers Guide section "Acquiring API credentials".

Implementation

This is a full HTML & JavaScript example. Add in your own AppId and Token and feel free to modify and use for your own purposes.
