Hi Tharik,
Good intiative!
I'd like to add few comments.
- Upgrade Vega version to 2.0
- Need to eliminate few shortcomings of the line chart. E.g Tooltip not
displaying at sometimes.
- Let advanced users to pass vega specifictions directly with the chart
configuration. This needs to be discussed further. This will allow users to
manipulate vega attributes directly like legend position, label font size
etc.
- Define standard methods like init(), draw() and update() for all chart
types. Enforce chart developers to implement them so that those methods can
be called by Vizgrammr at runtime.
- Keep the main interface of vizg object simple. E.g
vizg.draw("#canvas,chartConfig,dataTable)
- Remove the arc chart type.
It would be nice to improve the existing drill down capability of bar
charts and also find out other chart types that supports drill down.
Regards,
Dunith
