Examples

1. Product Performance Comparison

Marketing Analyst
Background
The analyst needs to compare the conversion rates of two different marketing campaigns across five regions.

Input the regional data with conversion rates for Campaign A and Campaign B, then select the 'Business' color scheme.
Example Config
chartData: [{"label": "North", "leftValue": 45, "rightValue": 52}, {"label": "South", "leftValue": 38, "rightValue": 41}, ...]
Outcome
A clean back-to-back chart clearly showing which campaign performed better in each specific region.

2. Budget vs. Actual Spending
