I've removed the "Adjust Parameters" section and everything below it from the ROI calculator. This includes:

1. The parameter adjustment sliders section with all its controls
2. The expandable controls area
3. The "How to use this visualization" information box

The ROI calculator now ends after the chart visualization section, providing a cleaner and more focused interface.

I'll update the label text from "Hourly Rate (per User)" to "Average Hourly Rate (per User)":

I've updated the label text to "Average Hourly Rate (per User)" as requested. This change helps clarify that the hourly rate represents an average value across all users rather than a fixed rate.
