This bar chart visualizes reported happiness levels in the Netherlands from 1997 to 2018, with each bar’s length representing the yearly "geluk" score. The chart uses D3 v5’s `scaleLinear` for the x-axis and `scaleBand` for the y-axis, rendering SVG rectangles with steelblue fill. Data is loaded from a local CSV file via `d3.csv`, and axes are generated using `axisLeft` and `axisBottom`. The visualization highlights slight annual fluctuations in happiness, remaining mostly stable between 87 and 89 points.
