p <- plot_ly(
  data = mtcars,
  x = ~wt,
  y = ~mpg,
  type = "scatter",
  mode = "markers",
  text = ~paste("Car:", rownames(mtcars),
                "<br>Weight:", wt,
                "<br>MPG:", mpg)
)

Conclusion

• Heavier cars tend to have lower MPG.
• The relationship is clearly visible in the interactive plot.
• Plotly allows zooming and hovering for detailed inspection.
