# Data visualization tool
A simple data visualization tool in web page. Currently it works as below:

1. Load data from a csv or json file.
2. Show data in table format, it provides page, sort and search functionalities.
3. Draw charts.
   * Allow to add more than one charts, and have more than one series in a single chart.
   * Allow to specify filter expression to exclude abnormal data records. 
   * Allow to specify group expression for the x axis. For example, we may want to show a chart per minute instead of per second.
   * Allow to specify left or right y axis for each serie.
   * Allow to specify aggregation option for y series. It is especially useful when there is group expression on x axis.

**Note: All expressions are actually javascript code. In exprssion you need to use "dataItem" to retrieve the data. It reprents a data record row.**
