This challenge is about the disappearance of certain employees of a natural gas production company, GASTech, right before its initial public offering. We have been provided with the following data and the main objective is to visualize this data, observe trends, patterns, or anomalies in the behavior of these employees and understand who was behind the kidnapping of employees:

  • GPS tracking data of each vehicle
  • Vehicle to employee mapping
  • Credit card and Loyalty card transaction information
  • ESRI shapefiles of Abila and Kronos, the city of this company

To visualize this data, we created the following visualizations:

Radial Bar plot and Radial Scatter Plot.
Car tracking using the GPS data on a map created using the shapefiles.
Left: (flowing through 3 images) A Sankey chart showing the number of occurrences a car and a credit/loyalty card were spotted together according to our algorithm. Right: Scattered Boxplot showing spending trends at each of the locations.
Left: Mapping of credit/loyalty card and employees. Right: Network Plot between employees and locationst.
