Interactive Plotly Chart

The chart below shows the relationship between car weight and miles per gallon using the built-in mtcars dataset.

plot_ly(
  data = mtcars,
  x = ~wt,
  y = ~mpg,
  type = "scatter",
  mode = "markers",
  text = ~paste("Car:", rownames(mtcars),
                "<br>MPG:", mpg,
                "<br>Weight:", wt),
  marker = list(size = 10)
) %>%
  layout(
    title = "MPG vs Car Weight",
    xaxis = list(title = "Car Weight"),
    yaxis = list(title = "Miles Per Gallon")
  )
