This example displays a minimal directed graph in which the node "Hello" points to two nodes, "Graphviz" and "VizHub". It renders the graph using the `d3-graphviz` library, which converts the DOT language text specification into an SVG visualization. The code creates the graph by calling `select("#graph").graphviz().renderDot(dotText)`, with fade animations disabled. The DOT source string is also injected into the page as text via `select('#dotText').html()`, allowing a side-by-side view of the graph and its defining code.
