// The following line selects all circles on the page and changes their stroke-width to 10 (px)
d3.selectAll("circle").attr("stroke-width", 10)

// Two slashes means "comment". Commented code is not run.
// It is good to comment your code so you remember what's going on.
// d3.selectAll("circle").attr("fill", "blue");

// The following lines deal with making selections and then sub selections within those selections
d3.selectAll("circle").attr("stroke-width", 10);
d3.select("#blue").selectAll("circle").attr("stroke","rgb(34,56,35)");
d3.select("#red").selectAll("circle")
