The Phillips Curve and the Philippines According to Cristeta B. Bagsic‚ the Phillips Curve “depicts the trade-off between inflation and unemployment rate” (“The Phillips Curve and Inflation Forecasting: The Case of the Philippines”). Nowadays‚ the relationship depicted by the Phillips curve is specified in the following equation: πt = πe – γ(UR – UR*) + v where πt is the inflation rate‚ πe is the expected inflation‚ γ is a parameter‚ UR is the unemployment rate‚ UR* is the natural rate of unemployment

When dealing with machine generated data‚ we often tend to see the data to have better understanding of a structural form. Many such data can be represented in the form of graphs. By laying out a graph‚ we can untangle information and intuitively show relations of objects. Automated graph drawing remains a difficult placement and layout problem. This problem
