I want to create 3 concentric arcs with line and labels with some HTML in the center.
One of the third arc overlaps the second arc. I want to add polylines with the labels to make it more descriptive.
below is the work done so far

I have the following 3d scene generated, with square "timber". I would like to add outlines to the shapes, but not show the triangles that make up the rectangles. Is that possible? I am also addind side walls, made out of different planks, but the problem is it looks like 1 big rectangle, instead of multiple planks. That's why I would like to show the outline of the rectangle, but don't want to show the triangles. I would like to do cartoon like lines.
Based on the answer provided by Prisoner849. I can now build my model with clear lines.
There are many ways to check is point inside path, but i haven't found any algorhitm which can check if the circle(whole object, not center point) is inside svg path.
If you're wondering why I need this algorithm - i want to fill space with circles with different radii (http://bl.ocks.org/mbostock/1893974), and those circles that enters the shape i want to paint in another color. As a result, we get the test image for color-blind people, like Ishihara's pictures.
The expected result like on that picture.
This a collition detection algorithm or intersection.
Step 1
Fill with cirlcles you base shape
Step 2
Create the main shape
Step 3
Detect interserct and color the shape behind. And hide the main shape
Pros: You can add dynamically shapes, animate or change it on the fly.

I am working on a multi-line animated chart based on [Edit: not Bostock's] example:
http://bl.ocks.org/atmccann/8966400
I want the lines to appear synchronized by the date value on the x axis. If I slow down the graph (say to duration=15000) I can clearly see that in the very early part of the graph the green line is ahead of the black line. Then the black line moves ahead of the green line. Both start and end together.
The issue is accentuated in my chart where I am plotting 20 lines. Some are clearly ahead of the others when plotting. Lines with initial y values of zero shoot way ahead of those that climb to higher y values at the start.
How can I adjust the display so both lines paint for the same date at the same time?
The technique in the bl.ocks.org example (which, btw, is not Bostock's) is animating based on the length of the line, not it's position on the y-axis. If you want to animate based on the y-axis position, you'll have to use a different technique. Especially with 20 lines, I wouldn't recommend trying to dynamically update each line if they have a lot of points. You could do that if there aren't many points, though.
A simple approach would be to add a solid (white) rectangle to the chart that covers all the graph lines. Then animate the left position and width of that rectangle to reveal the lines over time.
I'm looking to chart some time-based data over the course of multiple days (using a simple line chart). I'd like to present the time of day as a gradient of color in the background of the line graph. Noon of each day would be white, midnight is nearly black, and all other hours in between are a smooth greyscale in between.
I can do this very, very clunkily by drawing rectangles before my lines, but it has the following problems:
1. hours without a data point don't get a rectange, leaving a gap in my background
2. the transition is not smooth, but stepped
It seems that the best way to fill in the gaps would be to latch onto the ticks along the x-axis, as those are regularly spaced regardless of the data points. Is there a way for me to apply a gradient, either CSS or SVG, along with the tick marks, that will smoothly flow from one to the other (that is, no gaps between where one gradient ends and the other begins, nor any overlap)? If I add or remove data, the gradient should change accordingly.
Any and all assistance greatly appreciated.
just define the gradient in a <def> section, and place rectangles aligned with the days you are charting. set the fill attribute to url("#the_gradient").

I have a 3dpolyline and arc (3D). I 'm wondering if I can join 3dpolyline with 3d arc to get 3dpolyline. While seraching on this topic i found that I need first a routine that converts arc to 3dpolyline and then join two 3dpolylines. Does some one knows some link.?
A 3D polyline is a connected sequence of straight line segments created as a single object. 3D polylines can be non-coplanar; however, they cannot include arc segments.
