Spread the hummus evenly in a shallow bowl or directly onto the center of your serving board.
Drizzle the balsamic glaze in three or four concentric circles over the hummus.
Use a toothpick to drag lines from the center outward through the circles. This creates the spiderweb pattern.
Arrange the carrot sticks, cucumber rounds, bell pepper strips, broccoli florets, and celery sticks around the hummus in sections.
Place two black olives together near the edge of the hummus to form each spider. Use small pieces of another olive for legs if desired.
Repeat with the remaining olives to add several spiders across the board.
