A scatter plot is another type of visualization. It usually uses circles to map data points, which have two values each. These values tie to the x and y axes, and are used to position the circle in the visualization.
SVG has a circle tag to create the circle shape. It works a lot like the rect elements you used for the bar chart. Use the data(), enter(), and append() methods to bind dataset to new circle elements that are appended to the SVG.
Note: The circles won't be visible because we haven't set their attributes yet. We'll do that in the next challenge.
Waiting: Your code should have 10 circle elements.
