Hi,

I've to write a dashboard with real-time stats and I found DVL (via http://labs.metamx.com/ ). This library looks awesome but some question remains:

• Is it production ready ? (if not what will you recommend for making up real-time stats dashboard ?)
• Which browser are tested ?
• Is DVL maintained ?
• No documentation ?
• http://labs.metamx.com/js/_/dvl_realtime.js seems to offer some helpers for DVL like "instrument_histogram" and "instrument_graph" why aren't they included in the DVL project ? I think they could be useful for starters like me :)

Thanks for your time

Thank you for the feedback.

Q&A:

• Is it production ready?
  • Metamarkets is currently using it in-house to aid development, but we believe it is not production ready.
  • Some new graphing methods are being developed that remove complexity and make producing graphs a much smoother process.
• What do you recommend to use in the mean time?
  • I'd recommend using D3. DVL is an event framework built around D3. Knowing what attributes to use for SVG elements will translate directly to DVL in the coming months.
• Which browsers are tested?
  • We have successfully tested on Safari 5+, Firefox 3.6+, and Chrome. DVL is basically a wrapper to D3. So the bottleneck lies within D3.
• No documentation ?
  • Method APIs other than the core functions above are still fluid. Expect documentation to arrive when we feel it is ready for production use.
• No helper methods that produce plots?
  • Graphs are a VERY customizable thing. Many examples will be provided where you can steal from. It is very hard to get everything right with one function. (tick, grid, title1-title3, one data or N datas, line colors, transitions or multiple transitions.... etc)

Please keep watching the repo. We're setting a goal of 1-2 quarters for official release.

Thanks for all these informations !

For now I'll use rickshaw but I keep an eye on DVL ( labs.metamx graph's animations are just awesome !)
