From the same article:
Congress may define the jurisdiction of the judiciary through the simultaneous use of two powers. First, Congress holds the power to create (and, implicitly, to define the jurisdiction of) federal courts inferior to the Supreme Court (i.e. Courts of Appeals, District Courts, and various other Article I and Article III tribunals). This court-creating power is granted both in the congressional powers clause (Art. I, § 8, Cl. 9) and in the judicial vesting clause (Art. III, § 1). Second, Congress has the power to make exceptions to and regulations of the appellate jurisdiction of the Supreme Court. This court-limiting power is granted in the Exceptions Clause (Art. III, § 2).
