This visualization displays the chart positions of Madonna's top 10 singles over her career, using circles placed vertically by rank (1 at top) and horizontally by release date. Each song appears as a labeled dot; hovering reveals a tooltip with the song title, date, and rank, while clicking opens the corresponding YouTube video. The code uses D3 v4 to bind the gist data, scales the x-axis by date (using moment.js) and y-axis by position, and appends SVG circles and text. A separate info panel updates with the most recently hovered song's details, and the tooltip uses D3 event listeners to follow the mouse.
