MEGA TRICK: SVG in Coda (one step away from generated charts and mind maps!)

Just found one interesting place where SVG works but multiple Rectangle()s won’t — in detail layouts:

Here’s how the same progress bar looked when built with rectangles:

@Paul_Danyliuk good find, this looks so good! What does the code look like for a progress bar like this? Sorry, definitely not an expert in SVG :laughing:
Edit: This also opens the door to gradients and better looking progress bars :open_mouth:

Is there a site where you can generate SVG code? Thanks a lot :pray:

Edit 2: Found a few ones but would still love to know how you did it ahah

Gradients — totally possible. This exact layout is actually possible.

Online editors — not sure. But there’s a range of standalone vector drawing applications, from free (e.g. Inkscape) to paid (e.g. Affinity Designer, Adobe Illustrator) that export SVG. One downside is that they usually export a lot of extra metadata within the files. E.g. see the “organization chart” example in the doc in my original post — I simply copied the first copyright-free chart from Wikipedia I found, and perhaps 90% of its SVG code is redundant garbage that could easily not be there.

It is actually very simple to compose SVG by hand and include only the essentials. There are lots of tutorials. One of the knowledge sources on web technologies that I personally trust is MDN:

Here’s how I did that particular one. I already fed urlencoded SVG (prepared through my doc) to avoid unnecessary calculations, since it was simply about filling in one width value:

It’s just two <rect />s in an <svg />, no groups even.

I struggled with this in the Meeting Agenda template. The detail view wants to crop and size images to fit for some of the layout options and forces rectangles to squares. That’s why all the timer stuff is outside the detail view layout and in the canvas.

I might have to dig in and give this strategy a try.

Quick question - got a good example for doing a word cloud like this?

What do you mean exactly?

Looking for something like https://www.wordclouds.com/

Uhh… well, the complexity here is to come up with the algorithm to lay out the words (calculate x/y/size/rotation), then it’s as trivial as just concatenating all the <g transform=...><text>...</text></g>'s together.

No idea how to lay out automatically t the moment.

Hi @Paul_Danyliuk

Was inspired by your SVG post (thank you!)

I’ve been trying to find a quick way (for years) to create a simple product milestone view (I always made these in Google Presos).

Using your naive SVG method, I’ve created this: https://coda.io/d/Formula-SVG_dL1cBD5Vsag. It actually works really well (though there are lots of formatting improvements that could be made.

Now I have a problem though - The regex formula to convert to “naive SVG” format is really expensive and slow on a performance basis. Of the total compute time of 250ms, 210ms of that is coming from the regex formula (copied below for viz).

Any ideas for how to streamline the conversion step to SVG?

Here’s that REGEX SVG conversion formula:
Concatenate(
“data:image/svg+xml,”,SVG_output_combined_markup.RegexReplace("\n|\t", “”).Split("").FormulaMap(
CurrentValue.Switch(
" ", “%20”,
“<”, “%3C”,
“>”, “%3E”,
“#”, “%23”,
CurrentValue
)
)
)

Hey @Brandon_Trew,

Instead of converting the whole SVG every time, maybe “pre-convert” building pieces beforehand like I did in the tree map impl?

Take a look at Helpers: Chart settings section, HLP Templates table.

You can actually pre-convert them not in Coda but using some external tool and just save like that.

Love this. Really smart interplay between the tables and the formulamap. let me work on incorporating this. thank you!

@Paul_Danyliuk Finally putting your SVG revelations to good use!

One more SVG chart implementation. This time using paths and some basic trigonometry (polar → cartesian)

Time to revive this topic, lol.

Another freshly discovered capability: HTML & CSS in SVG, which gives us HTML & CSS in Coda!
