[Math] Drawing Direction Fields Online

online-resourcesordinary differential equationssoft-question

I am looking for a convenient and free online tool for plotting Direction Fields and Solution Curves of Ordinary Differential Equations. I tried the "Slope Field Plotter" on Geogebra; it worked tolerably well with direction fields, but for solution curves, some funny thing happens like this:

My Questions:

  1. Why does the solution curve appear to be very different from circles?
  2. Is there any alternative online free resources that will do a better job on this?

Edit:

I would love to use WolframaAlpha for this, if it works. Any suggestions on this?
