plotting a graph with different size markers

Hello everyone,
I would like to plot a graph with the data points as circles according to their sizes in diameter. The y-axis is the vertical distance and the x-axis is the horizontal distance. Furthermore, is it possible to colour the points from 1.53x10^-4 to 2.23x10^-4 in red and the rest in blue?
Thanks

Read about scatter.

I read about scatter but the problem is my x-axis is not in equal dimensions to scatter as far as I've understood it
data = xlsread("Data.xlsx") ;
x = data(:,1) ;
y = data(:,2) ;
z = data(:,3) ;
scatter(x,y,[],x,'filled')
data = xlsread("Data.xlsx") ;
x = data(:,1) ;
y = data(:,2) ;
z = data(:,3) ;
sz = linspace(1,300,length(z));
scatter(y,z,sz,'filled','MarkerEdgeColor',[0 0 1],...
'MarkerFaceColor',[0.5843 0.8157 0.9882],...
'LineWidth',1.5)
so that is my code but is there like a code to change the colour for half the values to red. For example there are 146 data points so from 74th data points onwards it should be red
Read about indexing.
data = xlsread("Data.xlsx") ;
x = data(:,1) ;
y = data(:,2) ;
z = data(:,3) ;
sz = linspace(1,300,length(z));
scatter(y(1:74),z(1:74),sz(1:74),'filled','MarkerEdgeColor',[0 0 1],...
'MarkerFaceColor','r',...
'LineWidth',1.5)
hold on
scatter(y(75:end),z(75:end),sz(75:end),'filled','MarkerEdgeColor',[0 0 1],...
'MarkerFaceColor','b',...
'LineWidth',1.5)
Thanks a lot for your help and recommendations. I've learnt a lot from you
