Graph data series with colors

Along with say hello, I am attaching a .txt, where the first column is the X axis, the second column is the Y axis, and the third column represents the magnitude.

What I need is a 2D graph of X vs Y, and with a colorbar (color scale) that represents the magnitude of the third column.

Thanks greetings.

load data.txt
scatter(data(:,1), data(:,2), [], data(:,3), 'filled'); colorbar;
