In this case this is a charting application, but any complex application that retrieves data from a database is possible. The communication with the database uses AJAX, so it works without refreshing the page. After retrieving the data, it can be presented in unlimited kinds of ways, and with JavaScript/AJAX the application can be interactive. The charts show daily (detailed) and monthly (sampled) charts. The sampled chart type is called candlestick chart.

The project consisted of a improvement of a D3 chart wrapper. I added the support for multiple line charts, multiple axis (left and right y-axis), a selector for zooming the chart and the background chart highlights for indicating important data selections. I also fixed some errors in the OOP design of the D3 wrapper.

This developer followed the spec and was also creative enough to understand where there may have been gaps in the spec. The work was well coded and matched my vision of what the new feature would be like.
