Current features and Ideas 

Plugins:
  • PluginChart, the first one, from spreadsheet data
  • PluginChartJS, added in Tiki16, if someone is able to make ti work
  • PluginPivotTable, added in Tiki16.2, and it can make some charts types also
  • PluginR also allows displaying graphs from data, through many of the packages for display and visualization of data: Lattice, ggplot2, gmaps, googleVIS (Google Visualization API), rCharts (PolyCharts), ...
  • PluginDBreport, which could be transformed to charts & graphs

Some key libraries 

Kibana 

Grafana 

d3.js 

Plotly.js 

  • Built on top of d3.js and stack.gl, plotly.js is a high-level, declarative charting library. plotly.js ships with 20 chart types, including 3D charts, statistical graphs, and SVG maps.
  • Plotly.js (MIT licensed):
    https://plot.ly/javascript/open-source-announcement/

pivottable.js 

MIT-licensed!

Vega 




Also:

  • Flare: http://flare.prefuse.org
    A priori desestimated because:
    • It uses Flash, it can be used with free compilers (like the Free Flex SDK), and it produces impressive graphs. But we don't have anyone in the community using it right now, so it looks as if it would be too hard to maintain.
    • it seems that the issue with visualization is not with the rendering engine as much as with gathering the data at this time (2011). For the rendering part, Raphael as used in sheets does a very good job.
    • some tiki devs would prefer to use some non-flash solution, e.g. something like http://thejit.org/ or the Raphael lib to visualise data in Tiki
    • flash animations are cool but it is too proprietary and problematic to code in an open source manner and make it accessible for everyone (you know, flash is not on iOS devices, requires 3rd party plugin in the browser, is cpu/memory resources intensive, etc.

When to use which type of chart
