Demonstrates how to use interactive URL links in TLatex.
JSROOT and standard SVG output support the syntax 'url[link]{label}'. This can be combined with other LaTeX commands, such as color or font settings.
Since TLatex is used in many contexts, external links can be added to histogram titles, axis titles, legend entries, and more.
This functionality is available only in web-based graphics and standard SVG output.
