This repo utilizes the npm express & net-ping packages to determine the external ip address(es)
of connections made to a webpage hosted on a specified port and then pinging them to acquire the
round-trip-time which is then plotted using plotly.js stream API. The accuracy of the RTT acquired
using net-ping is questionable according to documentation. Results for my application have
proven to show little deviation from results acquired using the Unix ping command, however, the
maximum level of precision achieved with net-ping is to the nearest millisecond while the Unix
command can achieve precision down to 1/1000th of a millisecond (this would also make the graph look
better). While using spawn to spawn a child process using Node.js would technically be preferable
in order to achieve this precision, handling of the resulting data is difficult given that it must be
retrieved from stdout.
