Read the feed programmatically and categorise the messages according to the sentiment (field: sentiment) of the message (field: Message). The messages should be displayed on a map and attached to the respective cities mentioned in the message.
Bonus: Extra marks will be given for prowess and effort on visualisation. How can the different sentiment categories be visualised on a map and how can time be factored in the visualisation?
