World Map
This interactive choropleth world map visualizes population data by country. Each nation is colored on a gradient from light blue to dark blue using a quantized scale, with darker shades representing higher populations. The map uses a Mercator projection and includes graticule lines. Hovering over a country reveals a tooltip displaying the country name and its population, formatted in a compact notation (e.g., 1.2B). The visualization was built with D3.js and TopoJSON, and is based on a gist by Varsha-Ravi with an MIT license, using an SVG rendering approach.

Amount of donation v/s Years for Australia
This is a line graph plotting the Amount of donation made by australia in various years. Initially the data base was queried to reduce the data set to only with the donations made by autralia, then using this reduced data set in blocks as the data we have drawn a line graph with years on the x-axis and amount in the y-axis.
**Similarly we can get graphs for amount of donation made v/s years for any other country just by changing the appropriate data set
