Render console.log() to browser javascript console instead of visualization? about r2d3 HOT 3 OPEN

Yes, your example does write "test" to the console. But if the output is not text, then it just has a generic return. To see this, let's simplify your code above:

// !preview r2d3 data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20)
//
// r2d3: https://rstudio.github.io/r2d3
//

var mysvg = svg.selectAll('rect').data(data);
console.log(mysvg);

which only sends the console,

[object Object]

I cross-posted on stack overflow, and someone posted the following workaround: including,

console = d3.window(svg.node()).console;

as the first line of the javascript gives an inspectable object, where you can expand its hierarchy like so,

Being able to inspect the actual objects like this can be very useful.

This should work correctly, console.log() gets printed to the browser console and also in the actual visualization.

For instance, consider the following example, notice the console.log() statement:

// !preview r2d3 data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20)
//
// r2d3: https://rstudio.github.io/r2d3
//

var barHeight = Math.ceil(height / data.length);

svg.selectAll('rect')
  .data(data)
  .enter().append('rect')
    .attr('width', function(d) { 
      console.log("test");
      return d * width;
    })
    .attr('height', barHeight)
    .attr('y', function(d, i) { return i * barHeight; })
    .attr('fill', 'steelblue');

This code triggers both, an update in the console and the visualization, notice the test message:

Could you perhaps provide the sources of your visualization since is probably specific to that particular code or environment?

Did this bug ever get fixed? This issue is kind of a deal-breaker for being able to effectively use r2d3. I've documented the issue here, if it's helpful:
