sqlite3

Currently we only support Upsert for CockroachDB. Implementing same for MySQL should be pretty straightforward as well.

Wonder if we can also use INSERT ON CONFLICT UPDATE for PostgreSQL to ensure operation with same signature also works.

Unlike all the existing charts that graph a string (most likely) against a number, this graphs numbers on both axises. So in addition to the configuration changes needed for passing the right field to chartjs, the PR for this should also change the "preferred type" to "number" for the x axis when the chart type is scatter plot.

Trying the code in https://github.com/uptrace/bun/blob/master/example/rel-has-one/main.go I'm having:

panic: runtime error: invalid memory address or nil pointer dereference

goroutine 1 [running]:

Currently, the node colours in the network graph seem somewhat arbitrary. Ideally, the node colours convey meaning... perhaps a gradient to denote distance from the current selected topic/node.
