When saving a scene as SVG, circles are translated to <path> elements. For example

import matplotlib.pyplot as plt

circ = plt.Circle((0.0, 0.0), 1.0, alpha=0.5)
plt.gca().add_patch(circ)
plt.autoscale()

plt.gca().set_aspect("equal")
plt.gca().set_axis_off()
# plt.show()
plt.savefig("out.svg")
   <g id="patch_2">
    <path clip-path="url(#p50a8cc0149)" d="M 236.16 295.488.
C 268.238967 295.488 299.008381 282.742891 321.691636 260.059636.
C 344.374891 237.376381 357.12 206.606967 357.12 174.528.
C 357.12 142.449033 344.374891 111.679619 321.691636 88.996364.
C 299.008381 66.313109 268.238967 53.568 236.16 53.568.
C 204.081033 53.568 173.311619 66.313109 150.628364 88.996364.
C 127.945109 111.679619 115.2 142.449033 115.2 174.528.
C 115.2 206.606967 127.945109 237.376381 150.628364 260.059636.
C 173.311619 282.742891 204.081033 295.488 236.16 295.488.
z
" style="fill:#1f77b4;opacity:0.5;"/>
   </g>

A better suited approach would be SVG's own <circle> element:

    <circle cx="236" cy="174.5" r="121" fill="red" />
