Two interactive panels explore anxiety and housing in London. A choropleth map colors boroughs by average house price, with a dropdown to select years between 2011 and 2019; clicking a borough reveals its Net Promoter Score (NPS) for anxiety and average house price. A linked line chart uses Vega-Lite to plot these metrics over time. The map is rendered with D3’s `geoPath` and `topojson`, with data loaded from TSV files.
