Any example on how to plot a chart based on data from sql ?

Plotting is generally done in the browser, so Node is only used as a web service to return data in a consumable format (e.g. JSON). I've had fun using d3.js and rickshaw for plotting. The Node considerations are to make sure that unnecessary browser page refreshes (ie queries) are eliminated (to reduce system load). Use a session pool in node-oracledb. Depending on your data requirements, look at using Oracle Database 12.1.0.2's JSON datatype support.
