Second paragraph 'We have a web page ...'

I bought this book 'SVG Essentials' ISBN 978-1-449-37435-8. You say you have a web page where you can fetch examples etc at https://shop.oreilly.com/product/0636920032335.do but this page does not appear to exist (even though the number matches this book). Nor does any higher level of that URL seem to work either.
I had to use Google to track down your code examples, which seem to be at https://github.com/oreillymedia/svg-essentials-examples/archives/gh-pages.zip
Many thanks - Graham.

Note from the Author or Editor:
The URL is correct; perhaps the O'Reilly "shop" domain was temporarily down when you tried.

However, the catalogue page is currently missing the link to the GitHub repository; that will be corrected.

As you discovered, the examples are available here:

ungenerate sample file

In the first set of data, the centroid location is outside the area of the polygon, and given that this is a convex polygon, it's likely incorrect.

In the second set of data, all the y coordinates are close to 37.82, except for the last point whose y coordinate is 378.826. I suspect this is a typo, especially given the location of its centroid.

Neither problem really matters as this ungenerate sample file data is not used further.

Figure 15-4

The thermometer temperature in Figure 15-4 contains spurious "Â" characters (capital A with a caret) before the degree symbol, i.e., "17°C / 62°F". Figure 15-3 correctly shows the thermometer temperature without these characters.

Examples 3-2/3-3

These examples should explicitly mention the conversion factor from mm to px. Leaving it out makes the location/size of the rendered rectangle pretty mysterious.

Also it isn't clear why the rulers don't show the full size of the <svg> element in all the diagrams in this section; in the case of a browser rendering the SVG wouldn't the full size of the <svg> element be displayed (assuming no external JS/CSS)?

Tip

The section on transforming from "regular" Cartesian coordinates is very useful but omits what I consider to be an important detail -- as do most other examples I find online. What if Ymin is not 0?

Then an extra translation is needed.

The transform becomes

translate(0,ymax) scale(1,-1) translate(0, -ymin)

If you publish another edition, I think this is not terribly obvious (it took me an hour to figure out, I'm embarrassed to say) and I think it would be worth including, at least in one of the "Tip" sections.

Example 11-2

In example 11-2, several elements are not closed.

The feGaussianBlur, feOffset, and first feMergeNode element should all be self closing, but the closing slash is missing.

line -3

The statement in the code: // ]]> is incorrect - this statement should not be commented out. This error is in the electronic edition too. The interpreter apparently ignores this statement and automatically completes the brackets - but this should still be corrected.

in the top most code block

The points for the arc the method "centeredToSVG" shall return are defined as (x0,y0) and (x1,y1).

y1 is never calculated, but y2 is defined as global instead. Pretty sure this should have been y1 right before largeArc is defined.

Table of Content missing in .mobi

Missing Content Table of the book in the final release in .mobi format.
In the pre-relese version there was Table of content at the end of the book, but now nothing :(
(I'm using Kindle 3 Reader)

Note from the Author or Editor:
This may have been an error in an interim build, but I am seeing the Table of Contents at the end of the book in the final .mobi version I have available. It doesn't show up in the "Bookmarks" list, but if you're using a reader that displays Bookmarks, you don't really need the Table of Contents!

Update: The reporter of the error says the problem still exists in the latest downloaded version.
