This example illustrates the dynamic programming concept of determining whether a target sum can be formed from a given array of integers, using two recursive approaches: a basic method and an improved memoized version. The visualization displays the result of checking whether 15 can be summed from [3,5,7] as true, alongside the memoization object that records computed subproblem outcomes. Rendered as static SVG text within a light gray frame using D3.js v5, the example highlights the efficiency gains of caching intermediate results.
