Really nice chart! Love the interactivity. I think it would be really useful to also be able to click the data-points/dates in the bottom chart to pick a date (instead of just using the "scrubber")
Maybe have a line on hover over the bottom chart and if i click on it the top charts shows me the play breakdown for that day? (Just a thought)
Description
This visualization explores how artists dominate the Spotify Global Top 200 through two complementary lenses.
Scatter plot
Each dot represents one artist on the selected date. The x-axis shows how many tracks that artist placed in the top 200 (breadth); the y-axis shows their combined daily streams on a log scale (depth). Artists with a single massive hit cluster on the left; artists occupying multiple chart positions fan out to the right. The top 5 artists by total streams are highlighted in amber.
Use the date slider to scrub through available dates and watch the landscape shift. Axes are fixed across all dates so comparisons are meaningful.
Concentration ratio
The line chart below tracks the share of total daily streams captured by the top 5 artists over time. A rising ratio signals increasing consolidation at the top; a falling ratio suggests streams are spreading more evenly across the chart. The amber cursor marks the date currently shown in the scatter above.
Breadth vs. depth
- Breadth dominance: an artist places many tracks simultaneously (e.g. an album release or catalogue resurgence), spreading their footprint across the chart without any single track being exceptional.
- Depth dominance: an artist owns a handful of very high-streaming tracks — one or two songs pulling outsized numbers relative to the rest of the chart.
As more days of data accumulate, the concentration ratio line will reveal whether top-artist dominance is a structural feature of the chart or varies meaningfully week to week.
