Jon is visiting New York City for the first time. He would like to make use of his stay by touring various places around the city. He wonders if there could be any system which helps him to find a most optimal route which covers as many tourist places as possible from his source to his desired destination point.
Luckily, we have Open Street Maps which contatins "tags" on each road describing it. More information about it can be found here, http://wiki.openstreetmap.org/wiki/Elements#Tag.
Now, you as a Software Developer, need to develop a system to solve his problem. Here are the things that will help you,
- a OSM Map data in XML format. This data contains a map of Manhattan, New York. You can find the description of OSM data format here, http://wiki.openstreetmap.org/wiki/OSM_XML
Using these, when a source and destination points are given, you need to find a route which has a maximum number of tourist places in it. Any of the following tags is considered to be a valid tourist spot.
- tourism
- attraction
- leisure
- natural
To draw a map, you can use Leaflet library, http://leafletjs.com/ which has OSM support.
We expect you to come up with a simple interactive map where Jon can give his source and destination and get a best possible route to enjoy his stay.

Leaflet version 1.3.1 tries to access the file Google.js in the following path:

but fails because the file Google.js is not present in the path: https://github.com/shramov/leaflet-plugins/blob/master/layer/tile/
