[sritchie]

• 30:

  • Adds emmy.mathbox, with functions for creating Reagent fragments that configure the components from MathBox.cljs for Clerk (no Portal yet!)
  • dev/emmy_viewers/mathbox.clj shows off a basic demo

Next:

#_['emmy.mathbox.plot/AxisGrid
      {:subdivisions 2
       :x-axis
       {:divide 5
        :unit Math/PI
        :base 2
        :label-maker 'emmy.mathbox.plot/label-pi}
       :y-axis {:divide 5
                :subdivisions 2}}]
