Hi, I would like to add a javascript representation to the class below. I
would like to have a circle drawn on a HTML5 canvas. Is this even possible?
The code below does not work and I do not know very much javascript. I
would be grateful for help. The code below executes, but nothing is drawn
in the cell. I have looked at the ipywidgets
<https://github.com/ipython/ipywidgets>, but it is not clear to me how to
modify the code below.
*class MyCircle(object):*
* def __init__(self, center=(0.0,0.0), radius=1.0, color='blue'):*
* self.center = center*
* self.radius = radius*
* self.color = color*
* def _repr_html_(self):*
* return "○ (<b>html</b>)"*
* def _repr_svg_(self):*
* return """<svg width="100px" height="100px">*
* <circle cx="50" cy="50" r="20" stroke="black" stroke-width="1"
fill="blue"/>*
* </svg>"""*
* def _repr_latex_(self):*
* return r"$\bigcirc \LaTeX$"*
* def _repr_javascript_(self): *
* s=( 'var canvas = document.createElement("canvas");' *
* 'canvas.height= 400;'*
* 'canvas.width = 400;'*
* 'var context = canvas.getContext("2d");'*
* 'document.body.appendChild(canvas);')*
* return s*
