Suppose you work for a rideshare company like Uber. How would you visually represent correlation between ride duration, ride fare and ratings?

To visualize the correlation between ride duration, fare, and ratings, I would use a combination of visual tools:

1. Scatter Plot: Plot ride duration on the x-axis and ride fare on the y-axis. Use the size of each point to represent the rating (larger points for higher ratings) and the color to distinguish between positive (e.g., green) and negative (e.g., red) ratings. This allows for direct observation of how duration and fare relate to each other and how ratings are distributed across these dimensions.

2. Heatmap: A heatmap can effectively display the correlation matrix between these three variables (duration, fare, rating). This would show the strength and direction of linear relationships, highlighting any significant correlations at a glance.
