A movable packed bubble chart is an extension of a scatter plot or a bubble chart that is primarily used to represent relationships between numeric data variables. However, through a movable packed bubble chart, we can work with multiple variables at a time. It is the visually most efficient method to understand the insights when the data is continuously updated. The passenger traffic movement chart is a movable packed bubble chart that represents the flow of passengers across Washington metro stations around the clock on a typical weekday. The movement plot shows the percentile of the population boarding the metro at each metro station in Washington at a given time in a day. The packed bubble chart shows 25 metro stations available in Washington and the total number of population boarding at each station by the end of the day through clusters and their percentile.
