Benefits & pitfalls to avoid
- Line-charts imply that data is continuously changing. If your data is discrete you might consider a bar-chart instead.
Create your own
- Area charts can be created in a range of standard data applications such as Excel.
- Base maps can be created in a range of desktop GIS applications such as MapInfo and ArcGIS.
