I would like to create a simple visualization whereby the circle (country) will increase/decrease in size(Base on the variables) with respect to time.
How can it be done on matlab with my current dataset ? I would want each circle to represent a country and the size of the circle will be determined by the value in that particular year. C1990 represents year 1990

You can use rectangle() to draw a circle if you want. The radius can be the number in your table. Use "hold on" and then plot a circle for every country. Then turn hold off, call cla() to wipe the plot clean, then plot them all again for the next year. Pretty easy.
