dvxCharts for JavaScript comes with a large number of predefined language packs and settings
for almost all popular languages. They are located in the installation package,
in the /js/i18n folder. Language packs are in the form of javascript files, containing
definitions for all strings in the chart that can be localized.
In order to use a particular language pack, you need to include the javascript language
pack to the head of your page after referencing the dvxCharts javascript file.
