<dd><p>Ellipses are normally drawn using an approximation that uses
eight cubic bezier splines. The error of this approximation
is 1.89818e-6, according to this unverified source:</p>

</div></blockquote>
<p>There is a use case where very large ellipses must be drawn
with very high accuracy, and it is too expensive to render the
entire ellipse with enough segments (either splines or line
segments). Therefore, in the case where either radius of the
ellipse is large enough that the error of the spline
approximation will be visible (greater than one pixel offset
from the ideal), a different technique is used.</p>
<p>In that case, only the visible parts of the ellipse are drawn,
with each visible arc using a fixed number of spline segments
(8). The algorithm proceeds as follows:</p>
<blockquote>
<div><ol class="arabic">
<li><p class="first">The points where the ellipse intersects the axes bounding
box are located. (This is done be performing an inverse
transformation on the axes bbox such that it is relative
to the unit circle – this makes the intersection
calculation much easier than doing rotated ellipse
intersection directly).</p>
<p>This uses the “line intersecting a circle” algorithm
from:</p>

<p>and it returns a tuple of a <code class="xref py py-class docutils literal"><span class="pre">Path</span></code> instance and a boolean
value. <em>path</em> is a <code class="xref py py-class docutils literal"><span class="pre">Path</span></code> instance along which the arrow

meaning as in <a class="reference internal" href="#matplotlib.patches.BoxStyle" title="matplotlib.patches.BoxStyle"><code class="xref py py-class docutils literal"><span class="pre">BoxStyle</span></code></a>. <em>linewidth</em> is a line width to be
