Systems and methods for data visualization are disclosed. An example method includes: detecting a first movement of a first User Interface (UI) element on a slider bar; determining that the first UI element is located within an active portion of the slider bar. The active portion comprises at least a sub-portion of the slider bar. The method also includes, determining that a second UI element is located within the active portion of the slider bar; determining a relative position of the first UI element to the second UI element; and assigning transaction priorities to a first entity identified by the first UI element and to a second entity identified by the second UI element based on the relative position. The method optionally includes causing a transaction involving the first entity and the second entity to be executed based on the transaction priorities.
