I'll simplify the graph to make it cleaner and more focused on the key comparison.

I've simplified the graph by:

1. Removing unnecessary elements:

   • Removed the Legend
   • Removed axis labels
   • Removed dots along the lines (except when hovering)
   • Reduced margins and padding

2. Simplifying the visual style:

   • Cleaner grid lines
   • Removed tick lines on both axes
   • Reduced the number of Y-axis ticks to 5

3. Streamlining the tooltip:

   • Made it more compact
   • Simplified the styling
   • Kept only the essential information

The graph now focuses purely on the visual comparison between the two savings accounts while maintaining the interactive hover functionality. This cleaner approach makes the dramatic difference between the two accounts even more apparent at a glance.

I'll make the bottom text dynamic so it updates based on where you're hovering on the chart.

Now the bottom text will dynamically update as you hover over different points on the chart:

1. When you hover over any year on the chart, the bottom text will update to show the comparison data for that specific year.
2. It will correctly use singular "year" when hovering over the 1-year mark.
3. When you move your mouse away from the chart, it will default back to showing the final year's data.

This makes the simulator more interactive and informative, as you can see the detailed comparison for any point in time by simply hovering over that part of the chart. The text updates in real-time as you move your mouse across the timeline, giving you a better understanding of how the savings grow over time.
