On this page, we provide
all non-circularizable connected arrangements of $n=5$ pseudocircles and
all non-circularizable digon-free intersecting arrangements of $n=6$ pseudocircles.
In addition, we provide some
non-circularizable intersecting arrangements for $n=6$ and some
non-circularizable digon-free connected arrangements for $n=6$.
The respective non-circularizability proofs can be found in
Arrangements of Pseudocircles: Circularizability
For details on the encoding and/or the visualization,

The four non-circularizable (bi)connected arrangements of $n=5$ pseudocircles
Note that the arrangement "n5_nonr_number1_intersecting"
is the unique arrangement among all intersecting arrangements of $n \le 5$
which is not circularizable.
