This chart shows the number of H-1B visa petitions filed per year, with bars representing the total count for each year. The visualization uses React components to render SVG elements, with D3 v5 providing the scales and data loading through the `csv` and `scaleBand`/`scaleLinear` APIs. Data comes from the Office of Foreign Labor Certification via a GitHub gist, and the bars are positioned using the x and y scales, with axis labels generated by custom React components.
