我正在處理一個大型網路（1k 節點，1M 連接），我想設定一個自定義初始縮放，因為標準縮放只關注幾個節點并且需要大量時間來實作目標比例（我可以查看整個網路）。
這是我的代碼：
library(networkD3)
p <- forceNetwork(Links = links,
Nodes = nodes,
Source = 'source',
Target = 'target',
NodeID = 'name',
Group = 'group',
Value = "value",
Nodesize = "size",
radiusCalculation = JS("d.nodesize"),
zoom = TRUE,
arrows = FALSE,
linkWidth = JS("function(d){return d.value;}"),
linkDistance = JS("function(d){return d.value*10}"),
charge = gravity,
opacity = 0.95,
fontSize = 24,
linkColour = "#424242"
)
customJS <-
"function() {
d3.selectAll('.node text').style('fill', 'white').attr('stroke-width', '.1px').attr('stroke', '#3f3f3f');
d3.select('body').style('background-color', '#15171a');
simulation = this;
simulation.stop();
for (var i = 0; i < 300; i) simulation.tick();
simulation.nodes().forEach( function(d,i) {
d.cx = d.x;
d.cy = d.y;
});
simulation.restart();
}"
g <- htmlwidgets::onRender(p, customJS)

uj5u.com熱心網友回復：
這是在渲染上設定比例值的最小化，可重現的示例...
library(networkD3)
p <- forceNetwork(Links = MisLinks, Nodes = MisNodes, Source = "source",
Target = "target", Value = "value", NodeID = "name",
Group = "group", opacity = 0.4, zoom = TRUE)
customJS <-
'function(el) {
d3.select(el).select(".zoom-layer").attr("transform", "scale(0.3)")
}'
htmlwidgets::onRender(p, customJS)
