This example demonstrates basic JavaScript syntax and DOM interaction within an HTML page, displaying a large “Some JS Basics” message as the primary visual element. It logs various expressions and values to the browser console, including arithmetic operations, a const variable, a let variable that is reassigned, and a property from an object literal. The page renders an empty SVG container (960 pixels wide) but performs no drawing or data binding with it, focusing solely on fundamental scripting concepts rather than data-driven visualization or external libraries.
