Filter empty requirements

[eosti]

It's very easy to accidentally create and then lose empty requirements requirements, and there's a number of them in the database right now. The "proper" fix would be removing them from the requirements database entirely, but it'd be nice to automatically filter out requirements with no name.

Hello @eosti,

Sure, it's possible to implement a feature to automatically filter out requirements with no name in the tree-visualizer. This can be achieved by modifying the ngOnChanges method in the OrgChartComponent class to also check if the node's title is not empty. Here's a sample code snippet:

ngOnChanges(changes: SimpleChanges) {
    const visibleList = changes["visibleList"].currentValue;
    this.diagram.nodes.each(node => {
        node.visible = visibleList.includes(node.data.id) && node.data.title !== '';
    })
}

In this code, node.data.title !== '' checks if the title of the node is not empty. If it is empty, the node will not be visible. This will effectively filter out any requirements with no name.

As for the current method used to display the nodes, the tree-visualizer uses the GoJS library. The nodes are displayed using a Diagram object from GoJS, which is assigned to the diagram property of the OrgChartComponent class. The diagram object's model property is set to the model input property of the OrgChartComponent class, which is of type go.GraphLinksModel. This model represents the nodes and links of the diagram.

You can find more details about this in the OrgChartComponent file in the repository.

Please let me know if you need further assistance or clarification.
