**Takeaways:**

- The SVG element can be thought of as an SVG Viewport window
- Things within the SVG Viewport's dimensions are visible
- Things outside of the SVG Viewport's dimensions exist but are not visible
- Math (Cartesian) Coordinate Space has the origin point (X=0, Y=0) at the bottom left
- SVG Coordinate Space has the origin point (X=0, Y=0) at the top left
- SVG Coordinate Space has the Y axis values increasing as it goes from the top of the SVG viewport to the bottom
- You can use D3 and the knowledge of the SVG Coordinate space to add SVG elements and define their attribute value pairs such that you can place things within the SVG Viewport
