/// 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.
