Bug: SVG Rendering Mismatch with BPC Data

The SVG rendering of the circuit is inconsistent with the BPC data structure regarding pin connectivity.

• schematic_port_2 is connected in BPC but renders as not_connected in the SVG.
• schematic_port_0 and schematic_port_3 are connected to unnamedsubcircuit31_connectivity_net1 in BPC, but render as connected to unnamedsubcircuit31_connectivity_net0 in the SVG.
  This discrepancy indicates a bug in the BPC to graphics conversion process, potentially masking actual circuit connectivity issues.
