Sqliteviz allows building pivot tables and visualizing them. To build a graph ## Requirements for result set
run a query to get data. Then open visualisation panel by clicking ![](./img/visualisation.svg)
in any of the two side toolbars and choose a pivot mode by clicking ![](./img/graph.svg).
A pivot visualisation has the following settings: To build a graph, a result set must follow the following requirements:
- Columns – choose one or more column names from the result set. The values in - the first column must contain JSONs (the rest columns in the result set will be ignored)
the chosen columns will be column names of the pivot table. - each JSON has a common key indicating if the record represents a node (value 0) or an edge (value 1)
- Rows – choose one or more column names from the result set. The values in the - each JSON representing a node has a common key with a node id
chosen columns will be row names of the pivot table. - each JSON representing an edge has a common key with the edge source and a common key with the edge target
- Order of columns and rows.
- Aggregator and its arguments – a function which will be used for pivot cell Each JSON can have more fields used for graph styling (read more in [Graph styling][#graph-styling]).
calculation. An aggregator can have from zero to two arguments. An aggregator
argument is one of the columns of the result set. ## Graph settings
- View – pivot table visualisation. It can be a table, a heatmap, a chart,
etc. See some examples of different views of the same pivot table below. Start building a graph by setting a mapping from your records to nodes and edge properties.
Go to `Structure` -> 'Graph' and set the following fields:
- Object type – a field containing 0 for node records and 1 for edge records.
- Node Id – a field containing node identifier
- Edge source - a field keeping a node identifier where the edge starts.
- Edge target - a field keeping a node identifier where the edge ends.
