3. plot bubble img

    function plot_bubble()
        fig=Figure()
        ax=Axis(fig[1,1];title="Bubble size: BodyFat",xlabel="$(feature[1])",ylabel="$(feature[2])")
        Box(fig[1,1];color = (:orange,0.1),strokewidth=0.5)
        scatter!(ax,data[!,1],data[!,2],markersize=data[!,3].*2,color=(:blue,0.2),strokewidth=3,strokecolor=:black)
        fig
        #save("Bubble-size-BodyFat.png",fig)
    end
