  === Charting Widget Component ===
- (*** TODO ***)
+ (*** TODO *** Need to provide more detail and/or more example for this)
+ 
+ In order to use the chart component, you need to create a dataMap variable 
and put the graph data information inside it. Then call the Chart component to 
draw the chart.
+ 
+ A good example is in: 
'''chukwa-0.1/src/web/hicc/jsp/single-series-chart-javascript.jsp'''. Inside 
the jsp file, it will open the database and read the data and call the Chart 
component and return the chart to the front end.
+ 
+ You can get your data from rest API or database, then call the Chart as below 
and return the object to the front end. (TODO: need to link to the Javadoc of 
the Chart component.)
