A scatter plot displays car model data with circles plotted according to continuous axes. The visualization uses D3 v7 with a unidirectional data flow pattern, where clicking any circle highlights it by changing its fill to white and adding a black stroke, while resetting all other circles to black fills without strokes. The rendering pipeline uses D3 selectors with `.join` operations to manage SVG circles, and the interaction is implemented through mouse click event listeners that update the selected state and trigger a re-render.
