Make plot interactive

[thatsIch]

Currently, the graphs are plotted as images and displayed directly. This makes it difficult to analyze the data. You should be able to hover over a community and see information of the community, respectively of the edge, node and maybe even zoom into the plot to analyze subgraphs.

You can achieve zooming by registering an event in the UI like double click

plotOutput("secondPatient",
            dblclick = "secondPatient_dblclick",
            brush = brushOpts(
              id = "secondPatient_brush",
              resetOnNew = TRUE
            )           
 )

and observe that event on the server side

observeEvent(input$secondPatient_dblclick, {
    brush <- input$secondPatient_brush
    if (!is.null(brush)) {
      ranges$x <- c(brush$xmin, brush$xmax)
      ranges$y <- c(brush$ymin, brush$ymax)

    } else {
      ranges$x <- NULL
      ranges$y <- NULL
    }
  })

the brush option allows us to select a specific range which needs to be zoomed in and rerendered on demand if wanted.

This was easily solved via the package visNetwork
