Pagerank Test
A scatterplot-style visualization displays PageRank results as labeled circles positioned along a horizontal axis. Each circle’s x-coordinate corresponds to its ranking, while its radius encodes the associated value, with larger circles indicating higher scores. The title appears centered above the plot. The code uses D3 v5 selections, `scaleLinear`, and `scalePoint` (though `scalePoint` is unused) to generate SVG circles and text labels from hardcoded ranking and value arrays.
