This visualization displays a horizontal bar chart comparing the number of users across various applications. Built with React and D3 v5, it renders data from a remote CSV file, loading and displaying the first 50 entries. The chart uses D3's `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis, with bars rendered as SVG `<rect>` elements. The code includes custom axis components and formatting, converting large numbers to abbreviated forms with `format('.2s')`, and provides tooltips showing the formatted user counts.
