Fork of Assignment_2_pie

This example compares population trends across countries using both a stacked area chart and a pie chart. The area chart displays population data from 1970 to 2022 across eight time periods, while the pie chart shows the 2022 population distribution. Both visualizations load CSV data via `d3.csv` and use D3’s `d3.stack`, `d3.area`, `d3.pie`, and `d3.arc` APIs. The code demonstrates rendering SVG elements with ordinal color scales and includes axis generation and legend creation.

Assignment_2

This example combines a stacked area chart of country population changes across eight census years and a pie chart of fictional product sales. The area chart uses `d3.stack`, `d3.scaleBand`, and `d3.area` to layer annual population data by country, with axis labels and per-layer value text rendered via SVG. The pie chart applies `d3.pie` and `d3.arc` to sales quantities, adding a legend with color-coded rects and labels. Both visualizations load CSV data asynchronously and render using SVG elements.

Assignmant2_D3

An interactive scatter plot of the Iris dataset lets users explore relationships between sepal and petal measurements. A button panel allows selecting which feature is plotted on the x- and y-axes, and the chart re-renders with d3.axisBottom and d3.axisLeft. Points are colored by species and drawn as SVG circles using d3.scaleLinear scales over the CSV data.
