To be implemented for the visualization component

[formidify]

Some functionalities good (but not necessary nor required) to implement for the visualization page:

• Instead of showing the piecharts by themselves by category, I want to add an inner circle showing the percentage of real vs. non-real for each category (for examples see https://www.highcharts.com/demo/pie-donut). Likely a more advanced charting library, such as highcharts.js need to be used instead. (I will try and implement this myself over the coming weeks, hopefully)

• Ability to download each chart (a nice function to have but a screenshoot would do)

• Time series data ranking. Specifically, every time user wants to add a new object from a category is added to the canvas in the time series plot, a (somewhat) random object is added. It will be nice to have some ranking for objects in the time series plot in terms of that. For example, items with the highest jump from year to year will be added onto the plot first. However, this functionality is also not too necessary, since user can also view the data in the data tables.
