Countries that receive aid from Australia

1. List the marks/channels used and the data/attributes they map to

The bar chart encodes two attributes using a line mark with the vertical spatial position channel for the quantitative attribute, amount of money, and the horizontal spatial position channel for the categorical attribute, country.

The country data type is an item since each country is an individual entity that is discrete. The amount of money data type is an attribute, which is some specific property that can be measured, observed, and logged.

2. Write an explanation of what the chart shows

The bar chart shows the countries that get aid from Australia and how much they got for all purposes in all years available in the dataset.

3. point out 1-2 interesting insights (i.e., things you learned from the chart)

I found that Cambodia gets highest amount of aid from Australia. Also, it is more than half of the total aid Australia gives, which means that Cambodia takes more than every other country combined.
