plot_interactive_dependency_graph: Plot an interactive dependency graph

Description

Creates an interactive network visualization of function dependencies using visNetwork. Nodes represent functions and edges represent function calls. The graph uses hierarchical layout with color-coding based on distance from the most-connected function.

Usage

plot_interactive_dependency_graph(dep_info, include_disconnected = TRUE)

Value

A visNetwork HTML widget displaying the interactive dependency graph. The widget can be displayed in RStudio Viewer, web browser, or saved to HTML using htmlwidgets::saveWidget().

Arguments

dep_info

List. Output from analyze_internal_dependencies_multi containing dependency information and function metadata.

include_disconnected

Logical. If FALSE, excludes nodes that are not connected to the center node (most-connected function). Default is TRUE.

Details

The visualization includes:

• Node colors: Functions are color-coded by their distance (number of hops) from the most-connected function

• Node shapes: Boxes for defined functions, ellipses for undefined/external functions

• Tooltips: Hover over nodes to see function arguments, return values, source file, and documentation

• Interactive controls: Zoom, pan, drag nodes, and navigation buttons

The center node (most-connected function) is fixed at position (0,0) and rendered in dark red. Other nodes are positioned using a force-directed layout.

Examples

# Create temporary R files with sample code
temp_file <- tempfile(fileext = ".R")
writeLines(c(
  "helper_function <- function(x) { x * 2 }",
  "main_function <- function(a) { helper_function(a) + 1 }",
  "another_function <- function(b) { main_function(b) }"
), temp_file)

# Analyze the file
dep_info <- analyze_internal_dependencies_multi(temp_file)

# Create interactive graph
graph <- plot_interactive_dependency_graph(dep_info)

# Show only connected components
graph <- plot_interactive_dependency_graph(dep_info,
                                           include_disconnected = FALSE)

# Clean up
unlink(temp_file)
