| 7a6f04e | Mike Bostock | 20 April 2011, 03:24:19 UTC | Cluster & tree layouts don't use `value`. These hierarchical layouts inadvertantly exposed the `value` attribute and default sort-by-value, even though they don't depend on a numeric node value to compute the layout. Additionally, the hierarchical layout would filter any nodes with nonpositive (or undefined) values, which was overly strict. Fixes #121. | 20 April 2011, 03:24:19 UTC |
| 7be9277 | Mike Bostock | 20 April 2011, 02:18:35 UTC | Don't normalize gravity. Gravity (by which I mean a spring connecting each node to the center of the layout) should not decay linearly as more nodes are added to the graph; otherwise, repulsive charge forces will overwhelm gravity. | 20 April 2011, 02:18:35 UTC |
| 83cb0f0 | Mike Bostock | 20 April 2011, 01:02:19 UTC | Fix simulation restarting. If the simulation cools and stops, we need to restart it, rather than just resetting the alpha parameter. So, it is useful to have both `resume` and `start` methods on the force layout. This commit also fixes a bug where mousedown events on draggable nodes would continue to propagate, interfering with other events (such as clicking to add a node). | 20 April 2011, 01:02:19 UTC |
| 48537d9 | Mike Bostock | 20 April 2011, 00:50:09 UTC | Don't postpone immediate timers. Previously, rescheduling an immediate timer would cause it to be postponed again by a minimum of 24ms. This is undesirable if the timer is being scheduled in response to user events, such as mousemoves, that can occur very frequently. Now we schedule an early callback once, and don't touch it if it's rescheduled. In addition, the timer loop is now smarter about switching between short and long callbacks. If there's a short delay (< 24ms) until the next timer fires, the timer will use requestAnimationFrame. For longer delays, setTimeout is used. | 20 April 2011, 00:50:09 UTC |

| 6804b1c | Mike Bostock | 19 April 2011, 20:47:19 UTC | Better force layout for dynamic graphs. You can now register the "drag" behavior on nodes multiple times, and the correct behavior will result. In addition, the gravitational force now handles coincident nodes, computing a small random force to separate the nodes rather than setting the position to NaN. To demonstrate the new support for dynamic graphs, this commit includes a fun example where you can click to add new nodes. Any existing nodes within a fixed distance to the cursor on click will be linked to the new node. | 19 April 2011, 20:47:19 UTC |
| 7abebef | Mike Bostock | 19 April 2011, 20:03:41 UTC | Better center gravity. Rather than applying gravity to the entire graph, we now apply it to individual nodes, such that disconnected nodes and subgraphs still have a tendency to drift towards the center. In addition, rather than using a standard gravitational force that drops quadratically with distance, we use a weak spring who force increases with distance. This makes the gravitational effect less noticeable near the center, and also makes the effect stronger the more the nodes drift from the center. To balance the center "gravity" with the repulsive charge force, we also normalize the strength of the gravity based on the number of nodes in the graph. | 19 April 2011, 20:03:41 UTC |
| fd804ce | Mike Bostock | 19 April 2011, 19:39:37 UTC | Better force layout. Use Barnes-Hut criterion (a fast multipole method) for approximating repulsive charge forces between nodes. This replaces the previous approach using Floyd- Warshall to compute the graph theoretic distance between all nodes, eliminating O(n^3) initialization time. Additionally, the charge force is now O(n lg n) per iteration rather than O(n^2). Using the center of mass of the graph, apply gravitional attraction towards the graph center (based on the layout size). This encourages the graph to stay near the center rather than drifting away. | 19 April 2011, 19:39:37 UTC |
| 587b1bb | Mike Bostock | 19 April 2011, 19:17:46 UTC | Use x+y objects for quadtree points. This makes the quadtree implementation more compatible with the force layout. This change is backwards-compatible; if the points are not specified as x+y objects, they are assumed to be tuples and converted to objects. | 19 April 2011, 19:19:04 UTC |

By using the `insert` operator, we can preserve the correct order. | 14 April 2011, 06:28:04 UTC |
| 126e625 | Mike Bostock | 14 April 2011, 06:13:06 UTC | Add d3.svg.diagonal. This is a utility for creating a Bézier curve between opposite corners of a rectangle. This is commonly used to draw smooth curves connecting parent and child nodes in a hierarchical node-link diagram. A projection may be specified which allows the curve to be transformed from polar coordinates. This commit also changes the semantics of the recently-added `links` method, such that the objects have `source` and `target` properties that match the default diagonal format. | 14 April 2011, 06:13:06 UTC |
| 8d7bd91 | Mike Bostock | 14 April 2011, 05:41:30 UTC | Add `links` methods to cluster & tree. This method can be used to generate an array of parent+child objects for a given array of nodes.

| 60b6a3d | Mike Bostock | 14 April 2011, 05:04:11 UTC | Simplify cluster layout. The `cluster` layout is now more similar to the `tree` layout, using a separation function rather than a group property. In addition, the breadth and depth properties are replaced with x and y, respectively, and scaled according to the size of the layout. I've updated the examples to make them more consistent, as well, including the pretty Bézier curves. In a future commit I'd like to take some of the duplicate code in the examples and move that into reusable methods. | 14 April 2011, 05:04:11 UTC |
| 222629a | Mike Bostock | 14 April 2011, 01:50:26 UTC | Text transitions. You can now use the `text` operator on transitions, which has the same effect as setting the text value at the start of the transition. This is nice if you have a delayed transition, and avoids a common gotcha. This commit also simplifies the implementation of the `text` operator using the standard `textContent` property. This isn't supported on IE8-, but we could potentially add support in the future using `innerText`. | 14 April 2011, 01:50:26 UTC |

| c29d4dc | Mike Bostock | 14 April 2011, 00:31:16 UTC | Better box chart transitions. Preserving object constancy across transitions is tricky! For example, what happens if we remove the whiskers in a transition? How do we join outliers? This commit makes a few assumptions explicit: 1. The `quartiles` function must return exactly three elements. This property must be specified as a function. 2. The `whiskers` function must return exactly 2 elements, or null if no whiskers are to be displayed. This property must be specified as a function. 3. The `domain` function must return exactly 2 elements, or null if the default domain should be used. This property can be specified either as a constant or as a function. We could generalize this chart to support more than two whiskers, but it doesn't seem urgent, and it would complicate the transition if the number of whiskers changes. In a related change, the `whiskers` function does not receive a third argument containing the quartiles; instead, this is made available by the `quartiles` property on the values array (the first argument). The outliers are joined using the `Number` key function. The outlier data is now stored as indices; this allows reasonable object constancy across transitions with outliers. Similarly, the tick labels for the quartiles are whiskers are now separated, such that the whisker labels can be added or removed without spurious transition. | 14 April 2011, 00:44:20 UTC |

I've left this out as I've assumed it's straightforward enough to pass in the appropriate `radius` function instead. Likewise, I think the existing hierarchy `sort` property can handle situations that `order` was intended for in the Protovis version. | 11 April 2011, 09:01:11 UTC |

| bf180dc | Mike Bostock | 09 April 2011, 20:46:25 UTC | Fix a transition bug in bullet chart. We were computing the tick join based on the (new) format function, but doesn't produce the desired effect: the new format is applied on the old data. Thus, the wrong join occurs if, say, the value 0.5 with the new format results in "0". The correct join compares the old text content to the new format value. | 09 April 2011, 20:56:28 UTC |
