I agree that web-based libraries are being released at a more frequent rate and with greater adoption than desktop APIs, but to suggest that native app development offers no data visualization libraries seems a bit naive.
I didn't say there are no data visualization libraries for native development. What I said is there is no equivalent to D3.js. I recommend taking a look at D3. It is not a charting library. There are charting libraries built on top of D3, but D3 is not your average charting package like MS chart control.
