+.SYNOPSIS
+	Ping a host continuously
+.DESCRIPTION
+	This PowerShell script pings the given host continously and shows the roundtrip times in a horizontal chart.
+.PARAMETER hostname
+	Specifies the hostname or IP address of the host to ping (windows.com by default)
+.PARAMETER timeInterval
+	Specifies the time interval in milliseconds to repeat the ping (1000 by default)
+.EXAMPLE
+	PS> ./ping-host.ps1
