World Population Growth: A information visualization with pointillistic representation

1. Introduction

This project depict the world population growth by year. It distinguishes itself by deploying a pointillism animation to represent population growth and density at the same time. To enable this the code calculates the number of dots to be filled in each territory based the ration given. Due to the insufficient computing power in calculating the random position of each dots in real-time the program preloads the verified coords of random dots on each territory based on Perlin noise. The ideal scale between the dataset and each single dot is 1,000,000 population to one single dot though any positive number is valid within the code.

2. Purpose

1. To propose an alternative way of representing regional population instead of choropleth mapping method.
2. To combine two relevant data— population density and population growth on the same visual space.
3. To deliver the significant events in the population growth timeline together with the quantitative information.
