This visualization displays a bar chart ranking the top ten geographical areas by nitrogen dioxide (NO2) levels, with bars colored steelblue and labeled axes for geographical area and NO2 concentration in parts per billion. The code filters and sorts input data by descending NO2 values, then uses D3’s `scaleBand`, `scaleLinear`, `axisLeft`, and `axisBottom` to render the SVG. It leverages the `viz` function from `@curran/axis-labels` for reusable axis components, with data loaded from a linked dataset.
