This example displays a static SVG scene with a large blue rectangle and the text “Hello Parinaz!?” centered on the page. The page uses D3 v7 loaded via a script tag, along with custom CSS to style the message. The SVG element sets explicit width and height attributes, while the body uses inline styles to remove margins and hide overflow. No interactive behaviors or data bindings are present; the visualization relies solely on static SVG markup and CSS layout.
