PCAP Python analyser with JSON d3 visualisation

I have been in a few environments where installing a full blown PCAP analyser is just not possible. Therefore I created a Python script that will go through a PCAP file, split up IP flows and spit it out in a JSON format. This depicts TCP and UDP flows with the amount of traffic uploaded and downloaded, it also attempts to map IP addresses to domains using DNS requests found in the same PCAP file.
