1. A method for visualizing data associated with an electrical circuit design (ECD), the ECD having circuit variables and circuit performance metrics, the method comprising steps of: accessing a database containing circuit simulation data of the ECD, the circuit simulation data including circuit variables data and circuit performance metrics data; extracting circuit simulation data to obtain extracted data; processing the extracted data in accordance with a pre-determined data-mining algorithm to obtain output data; organizing the output data in accordance with pre-determined display criteria to obtain organized data; and displaying the organized data.
