%% Vary Circle Size
% Create a scatter plot using circles with different sizes. Specify the size in points squared

x = linspace(0,3*pi,200);
y = cos(x) + rand(1,200);
sz = linspace(1,100,200);
scatter(x,y,sz)

% Corresponding elements in x, y, and sz determine the location and size of each circle. To plot all circles with the equal area, specify sz as a numeric scalar.
