I am trying to extract data from mongodb using bottle in python and use d3.js to visualize it!Mongodb-->Python-->d3.js :     import bottle, pymongo  
    from pymongo import MongoClient 
    client = pymongo.MongoClient(some URI)  
    db = client['database']  
    dbcoll = db['collection']  
    @bottle.route('/hello')  
    def grab_record(name):  
        bottle.response.headers['Access-Control-Allow-Origin'] = '*'  
        return dbcoll.find_one({'_id':False})  
    bottle.run(host='localhost', port=8080, debug=True)  

On opening http://localhost:8080/hello, this is the error I get
