How to change size of plot points

Trying to make the points smaller so it is easier to read. I know about LineWidth, but is there a way to just make the circles smaller?

savtotal=1000; % initial amount
hold on
xlabel("Time (Months)") % graph labels
ylabel("Amount Saved ($)")
title("College Savings")
for i=1:216 % 216 months (18 years)
    savtotal=(savtotal+100)*1.005; % $100+interest each month (0.05%)
    plot(i,savtotal,"o",linewidth=0.1) % plot money each month
end
hold off
