  The CLS Orbit Cor­rec­tion (OC) sys­tem ac­quires, col­lates, and pub­lishes stor­age ring beam cen­troid po­si­tion in­for­ma­tion from 48 beam po­si­tion mon­i­tors (BPMs) at a rate of 1000 sam­ples per sec­ond. We pre­sent a "Stor­age Ring Beam Po­si­tion Vi­su­al­iza­tion Tool" that com­putes and dis­plays dy­namic Fast Fourier Trans­forms (FFTs) and Cu­mu­la­tive Power Spec­tral Den­si­ties (CPSDs) for all BPMs in real-time using full res­o­lu­tion data. The com­puted FFTs and CPSDs can be plot­ted in var­i­ous com­bi­na­tions and in wa­ter­fall plots that allow vi­su­al­iza­tion of changes over long pe­ri­ods of time. In ad­di­tion, cor­re­la­tions be­tween all BPM chan­nel com­bi­na­tions are com­puted and ranked. Data from any two BPM chan­nels can be se­lected for plot­ting in two di­men­sions wherein cor­re­la­tions are vi­su­ally ap­par­ent. Com­puted CPSDs are fur­ther binned and pub­lished in scalar EPICS PVs which are archived for fur­ther analy­sis. Pre­lim­i­nary re­sults from the Beam Po­si­tion Vi­su­al­iza­tion Tool have proven use­ful in char­ac­ter­iz­ing beam po­si­tion noise at the CLS.
