I have an HTML/Javascript application which displays a line graph, a
gauge, a map chart and a table chart. This works fine on Internet Explorer 11
& Chrome on Windows 7.
When I try it on Linux (Ubuntu 16.0.4), in Firefox,
Chromium and Chrome the map chart is not displayed, however the line
chart, gauge and table chart are displayed correctly.
I'm pretty new to HTML/Javascript so any help would be greatly appreciated.
