Narrative:

On climb out I (first officer) happened to notice a wisp of smoke coming from under the ACARS area of the instrument panel. After a short time we began to smell a slight burning odor. We decided to return to the departure airport. The smoke and odor stopped. We continued to return; ran the QRH checklist and declared an emergency. We did an uneventful overweight landing. We entered both the overweight landing and smoke in the logbook.
