This D3 bar chart example displays Nobel Prize winner counts by country, filtering out zero values and initially showing all nations before updating to display only the first three. The visualization uses D3 version 7.8.5 with SVG rendering, applying the `join()` method on a selection to handle the incremental update of bar elements. The code demonstrates scaleBand and scaleLinear for axes, custom axis styling, and programmatic data filtering that triggers a second chart update.
