Easiest method for combining elements made in Angular with D3

Exploring various methods to combine D3 and Angular for learning purposes, seeking advice on the approach:

The client application is fed a JSON array of nodes and edges from the server. The main component is a graph visualization using D3 force-directed layout: Each node in the nodes array is represented by an SVG circle in this visualization, connected with lines according to the edges array.

Although D3's selection.data( ) makes it easy to add and bind elements to their data, integrating these elements into different parts of the application beyond the graph poses a challenge, as I aim to keep all elements tied to a single dataset.

Simplifying code complexity is my priority. While D3 offers elegant data-binding functionality, mixing it with Angular might create unnecessary complexity. Considering using Angular exclusively for data-binding and element creation across the application for consistency.

Instead of relying on D3's

selection.data( ).enter( ).append( )
, contemplating utilizing ng-repeat="node in nodes" within custom directives. Integrating these elements into D3's force-directed layout while ensuring smooth transitions poses a concern. Seeking recommendations on seamlessly merging angular-created elements with D3 for fluid motion.

Additionally, considering executing D3 for SVG element creation within the compile function rather than the link function of the visualization directive. Exploring potential benefits or drawbacks of this approach compared to the previous strategy.

Answer №1

After careful consideration, I have reached a solution to a problem that has been on my mind for quite some time.

To seamlessly integrate Angular-created elements with d3, the easiest method is to add directives using .attr and then utilize the compile service by calling it on the d3-generated elements. Here's an example:

mySvg.selectAll("circle")
                .data(scope.nodes)
                .enter()
                .append("circle")
                .attr("tooltip-append-to-body", true)
                .attr("tooltip", function(d){
                    return d.name;
                })
                .call(function(){
                    $compile(this[0].parentNode)(scope);
                });

In my opinion, creating elements with Angular's ngRepeat instead of d3 goes against the essence of the frameworks. D3 excels at taking data (usually in array form) and converting it into various SVG or HTML elements efficiently. It's best to let D3 handle this task.

Your statement suggests that generating elements with d3 might hinder binding the same data to different parts of your application. However, there shouldn't be any issues with this approach. Simply let d3 create elements from a scope array, like demonstrated in the provided Plunker. Then, you can use the dataset throughout your application as needed in the typical Angular manner. Updates to the dataset by other parts of the application can trigger a $watch callback to re-render the d3 visualization.
