A visualization constructed using the vega-lite-api. The viz shows the correlation between two important evaluation metrics 'Tax Burden' and 'Government Integrity'.

• We cannot seen a clear correlation between these two attributes. Tax burden is not significantly correlated with government integrity.
• However, most of the countries in the world have high tax burden as well as low government integrity, with a intenser field appearing on the right lower corner of the picture.
• Most European countries, the red circles on the picture, have a low tax burden and high government integrity, while most sub-saharah African countries, the green circles, have a high tax burden and low government integrity.
• An interesting outlier is located at the left lower corner, which is North Korea. The country has no tax burden but relatively low government integrity.
