I wanted to draw this graph. If someone could help me with the MATLAB code for this graph with a brief explanation about it?

I apologize, but could you please clarify the specific method or approach you are having difficulty with when searching for example codes on the Internet?

"I am not able to do it this way."
@simran, which way?

this could work
theta = linspace (-pi/4,pi/4);
x = 0.5*cos(theta).*sqrt(2.*cos(2.*theta));
y = 0.5*sin(theta).*sqrt(2.*cos(2.*theta));
plot(x+0.5,y,-x+0.5,y), grid on,
axis ('equal')
figure;plot([x+0.5 -x+0.5],[y y])
axis equal; grid on;

How about the black dots on the right?

@simran, What are the formulas to determine the coordinates for the "black dots"?
Also, when to apply the parameters {, } and {, } in the "Lemniscate" code?
