Once again using the trend of displaying information using a circle. Circles are commonly used for information that has the measurement of time because it is continuous. It often breaks the circles into different segments and different contours.
However with this piece I find it very confusing to extract information because there are so many lines and circles. I think the designer added so many circles and lines to embellish the piece and make it look impressive which can make it look more like a piece of visual art.
