This example of an Origin Bubble + Color Mapped Plot depicts earthquake data, both magnitude (bubble) and depth (color map). A Color Scale legend is included to clarify the meaning of each symbol color. A custom legend is included at the bottom of the graph to indicate the magnitude associated with each symbol size.
The earthquake data was obtained by downloading and installing the Earthquake Study Kit here: http://www.simplecodeworks.com/kitmenu.html. The actual data file is located in the \Quakes\DATA\ folder. Additional information can be found on the site here.
The World Map you see underneath the earthquake data was downloaded in the OriginLab File Exchange. The File Exchange submission is called "World Geographic Data". It is located in the "Other" category.
