- I also did not know how to do the transition for the chart
- Also, my bars on the chart were displaying but now there not`

Purpose-built for displays of data
Observable is your go-to platform for exploring data and creating expressive data visualizations. Use reactive JavaScript notebooks for prototyping and a collaborative canvas for visual data exploration and dashboard creation.
