[Python] Plotting graphs in C++

I have made the following graph using matplotlib in python.I have also attached the code I used to make this.

The code for the arena

import matplotlib.pyplot as plt
import matplotlib.patches as patches

obs_boundary = [
[0, 0, 10, 600],
[0, 600, 900, 10],
[10, 0, 900, 10],
[900, 10, 10, 600]
]
obs_cir_own = [
[50,500,10],
[100,300,10],
[240,240,10],
[300,400,10],
[190,50,10]

]
obs_cir_opp = [
[700, 420, 10],
[460, 200, 10],
[550, 500, 10],
[670, 70, 10],
[800, 230, 10],
[600,300,10]
]
fig, ax = plt.subplots()

for (ox, oy, w, h) in obs_boundary:
print(ox, oy, w, h)
ax.add_patch(
patches.Rectangle(
(ox, oy), w, h,
edgecolor='black',
facecolor='black',
fill=True
)
)

for (ox, oy,r) in obs_cir_own:
ax.add_patch(
patches.Circle(
(ox, oy), r,
edgecolor='black',
facecolor='green',
fill=True
)
)
for (ox, oy, r) in obs_cir_opp:
ax.add_patch(
patches.Circle(
(ox, oy), r,
edgecolor='black',
facecolor='red',
fill=True
)
)

plt.plot(50,50, "bs", linewidth=30)
plt.plot(870, 550, "ys", linewidth=30)
name='arena'
plt.title(name)
plt.axis("equal")


So, I want to implement a similar arena using C++ and I have no idea how to do it? I researched I got to know something about qtplot again I dont know much about qt. So, is qtplot the only way or there are some easier way. Please tell me how to implement this in C++.
