This scatterplot visualizes Berlin's population data across LOR planning areas, with each point representing a district's demographic profile. Users can dynamically select which age group or population metric to plot on the X and Y axes via dropdown menus. The visualization leverages React for interactive state management, D3 v5 for scales and CSV data loading, and SVG rendering for the plotted points. A color legend encodes Berlin's districts, while tooltips reveal exact values for each data point. The data comes from official Berlin statistics on residents by LOR planning area as of December 31, 2020.
