Simple Bar Chart

This SVG bar chart displays the population of the ten most populous countries, based on 2018 estimates from the United Nations' World Population Prospects. The chart uses a horizontal layout, with country names on the y-axis and population values on the x-axis, rendered as steelblue bars. The visualization is built with D3 v5, using `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis, with axes labeled via `axisLeft` and `axisBottom`. Data is loaded asynchronously from a CSV file.

Dynamic Bar Chart

This dynamic bar chart visualizes crimes against women in India, showing the number of assault cases for each state in a selected year. A dropdown menu lets users switch between years, while bars transition smoothly to updated values and re-sort in descending order. The visualization uses D3 v7 APIs including `csv`, `rollups`, `scaleLinear`, and `scaleBand`, with `transition` and `easeLinear` for animation. Bars change opacity on hover, and value labels appear at the end of each bar. The dataset comes from a CSV hosted in a GitHub gist.
