The road which has high COx concentration are cross jucntion in downtown (west side of Pasar Klewer), cross junction of Yos Sudarso street, Slamet Riyadi Street, and cross junction of Hay Lay (Wates). The used of pie-graph and bar-graph symbols produce more interesting map visually, but unfortunately the symbols cover up the information in their based map.
