/* Question-Based Learning Graph Update - Stylesheet
 * ==================================================
 *
 * GRAPH POSITIONING NOTES:
 * ------------------------
 * The graph network position is controlled by TWO areas in question-color-update.js:
 *
 * 1. NODE POSITIONS (nodeData array):
 *    Each node has x, y coordinates that determine its position relative to
 *    the canvas center (0,0). Negative x values move nodes left, negative y
 *    values move nodes up.
 *
 * 2. CAMERA/VIEW POSITION (positionView function):
 *    The moveTo() call sets where the camera looks at the graph:
 *    - Lower x value = moves the view RIGHT (shows more of left side of graph)
 *    - Higher y value = moves the view UP (shows more of bottom of graph)
