Sigma.js выбирает и перетаскивает несколько узлов из проанализированного gexf
Я пытаюсь адаптировать ссылочный пример выбора и перетаскивания узлов, чтобы получить ту же функциональность при загрузке узлов и ребер графа из .gexfфайл. В примере для ссылки выше создается граф со случайными узлами и ребрами, ср. Пример кода ниже:
var i,
s,
N = 100,
E = 500,
g = {
nodes: [],
edges: []
};
// Generate a random graph:
for (i = 0; i < N; i++)
g.nodes.push({
id: 'n' + i,
label: 'Node ' + i,
x: Math.random(),
y: Math.random(),
size: Math.random(),
color: '#666'
});
for (i = 0; i < E; i++)
g.edges.push({
id: 'e' + i,
source: 'n' + (Math.random() * N | 0),
target: 'n' + (Math.random() * N | 0),
size: Math.random(),
color: '#ccc'
});
Но как мне получить фактические (и количество) узлов и ребер из моего файла gexf? Мой файл gexf minitext.gexf выглядит следующим образом:
<?xml version='1.0' encoding='utf-8'?>

Теперь, если я попытаюсь объявить переменную графа g как
var g = sigma.parsers.gexf('data/minitext.gexf',
{container: 'graph-container'});
и примените к нему алгоритм ForceLink, в моем окне браузера ничего не визуализируется (используя Firefox). Когда я снова использую пример кода со случайно сгенерированным графом, он работает (также с макетом ForeLink). Пару часов я пытался заставить это работать, но все еще ничего не достиг. Я был бы очень признателен за помощь здесь.
Вот мой модифицированный код:
