Using the r2d3 package, I can render a simple d3.js chart in RMarkdown like this:

barchart.js:

// !preview r2d3 data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20) var barHeight = Math.floor(height / data.length); svg .selectAll("rect") .data(data) .enter() .append("rect") .attr("width", function (d) { return d * width; }) .attr("height", barHeight) .attr("y", function (d, i) { return i * barHeight; }) .attr("fill", "steelblue");

RMarkdown:

{r out.width='100%', fig.height=4} library(r2d3) r2d3(data=c(0.3, 0.6, 0.8, 0.95, 0.40, 0.20), script = "barchart.js")

However, let's say I want to draw the same chart simultaneously in RMarkdown (i.e. two charts side by side). Is there a way to do this? Using simple RMarkdown is easy since you can save the graph and then arrange it in a grid. But is there a way for r2d3 to do this? It does not save each shape as an object that can be arranged in a grid.
