Create a new tab titled "Dashboard." This tab will have two visualizations connected with a slicer. The first visualization will be a column chart showing the average number of seconds per sighting by year. The second visualization will be a column chart showing the average number of seconds per sighting by state. The slicer will use the field titled "shape" from the original data set. You will know that your answer is correct if both visuals change when the one slicer is changed.
