Very basic question: when using PlotlyJS with the Blink display window, how can I get subsequent calls to `plot()` to reuse the same Blink window rather than opening new windows?

Hello,  
One way is first to call ` deletetraces!(p,0);` and then `addtrace!(p,plt)` where plt is the plot.

A simple example

```julia
using PlotlyJS
# Data 
x = 1:10
y = randn(10)
# Plotting data 
pl1 = PlotlyJS.scatter(; x,y, name=" ");
p = PlotlyJS.plot(pl1)
# New data and update plot 
y = randn(10)
deletetraces!(p,0);
pl1 = PlotlyJS.scatter(; x,y, name=" ");
addtraces!(p,pl1)

```
