The designing of a simple three qubit system using Qiskit Metal.
Description
Using Qiskit Metal, design a single plane, three-qubit chip using superconducting qubits, which are coupled together to each other with a coplanar waveguide (CPW) bus resonators, and with each qubit having a CPW readout resonator. The readout resonators should be coupled to transmission line(s) which connect to launcher pad(s) for wire bonds. The qubits can be from the Metal qlibrary, or newly created qcomponents.
The project members are to determine the actual physical layout, with the below target parameters in mind. Try to land within +/-5% of targets.

Be mindful of potential cross talk issues between busses when deciding frequencies for your busses, and where in the available range to set your qubit and readout frequencies.
The project members can also decide on the chip size, though should consider issues such as, potential box/substrate modes, or cross talk between the different components on the chip. It can be assumed wirebonds are available to be added where desired.
If new qubit qcomponents are created for this project, some modification to analysis code may also be required (eg. LOM analysis code currently presumes floating transmons, but can function with grounded transmons with minor modifications).
Documentation showing the successful simulation/analysis of the chip design meeting the desired parameters. Explanations on design choices should also be included where appropriate.
