fresh block
This simple example displays the static text “First fun with blockbuilder.org!!!” in a monospace font on an empty SVG canvas. The visualization uses D3 v4 to select the HTML body element, append a 960-by-500-pixel SVG, and add a single text element at specified x and y coordinates. The code relies on d3.select, d3.append, and SVG text attributes to position and style the message, with no data source or interaction involved.
