Think of carbon atoms as colorful building blocks or snap-beads that can link together end-to-end to form extremely long necklaces, branched trees, or closed loops of varying sizes.

C-C-Chain = Catenation (Carbon's Connecting Capability)

Catenation is the self-linking property of an element by which a chain of identical atoms is formed. Carbon shows catenation to a maximum extent among all elements (except silicon to a lesser extent) due to its small size and high carbon-carbon bond enthalpy ($348 \text{ kJ mol}^{-1}$), which allows it to form stable long chains, branched structures, and rings (both single and multiple bonds).
