I am trying to add numbers and labels to this scatterplot

clc
clear all
close all
%reading the file
[numbers text]=xlsread('homelesspopinamerica.xlsx');
%manipulating withthe data and storing it at our convenience
statenames=text(2:51,1:2);
pop=numbers(1:50,:);
states=statenames(:,2);
state=statenames(:,2);
homepop=pop(:,2);
homeperc=pop(:,4);
totpop=pop(:,3);
states=categorical(states);
%create scatter figure
figure
scatter(homeperc,totpop,homepop/20,states,'filled')
title('HOMELESSNESS IN AMERICA 2017', 'fontsize', 36);
set(gcf,'color','w');
xlabel('Percentage of Homeless Indviduals')
ylabel('Total Population (millions)')
axis([0 0.6 0 4.5e7]);
grid on
%make graph large
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);

i want to label them by total homeless population (column D in excel sheet) and by state abbreviation (column B) and have the label inside the bubbles that it fits into. how can i do this? here is an example of what i am looking for:

There's a function called:
that is used for labeling data points in plots.

Hi Pawel, thanks for the info. Is there a way to use the text function to add labels only to the larger bubbles in the plot? Thank you!

Only call it for those locations.
[~, popsortidx] = sort(homepop, 'descend');
best10idx = popsortidx(1:10);
locx = homeperc(best10idx);
locy = totpop(best10idx);
beststates = states(best10idx);
saved_text = text; %save the variable that was badly named text
clear text %make way to use the function
text(locx, locy, beststates); %put up the text at the given locations
text = saved_text; %restore the badly-named variable text
