This example shows a minimal, static visualization composed of a single filled circle rendered inside an SVG canvas, with no interactive or animated behavior. The code builds the graphic using the D3.js v5 library, selecting the body element and appending an SVG container with a circle element; the circle’s radius is set but its center coordinates are misspelled as “cv” and “cy,” leaving it positioned at the default top-left origin. The page also includes CSS class “.barras div” suggesting a bar-chart styling, but no bars are generated. The rendering approach relies on D3’s selection and DOM manipulation methods, with no data loading or complex scales involved.
