In the case, the client is talking to a web server on the LAN without access to internet
(because of temporary failure),  the vizualization API is not available anymore. This
is a really important limitation in our context.

Slow internet connections and offline usage are key features for me. I'm using viz for
two projects (via GWT), but have to remove in both for each of the reasons. The serving
of js with cache private; max-age=0 doesn't help either (pay the cost on every startup,
jsapi is set to 1 hour max-age).

would be really great to see this feature implemented

Would like to put this product on a closed network for govt use. Cannot use as is.

I am in the same position as comment 5. Great framework but unusable in current state
for closed networks.

Same issue here : offline usage is a must-have feature for me.

I also want this issue to get resolved.

I need off-line use for moments when the remote libraries are off-line. Like a "plan
b"

This online restriction is a really bad news, as it is NOT clearly explained when you
use it. This is probably the reason why GWT visualization is not so spread and used,
although it's a great framework.

Can someone from google explicitly tells us if Google plans to change its terms or
not ?

Thanks

@juli1, I think we're more likely to win the lottery than getting a statement from google
on this ;-)

Original issue reported on code.google.com by d.alvarez.debrot%crazy-development.com@gtempaccount.com on 2011-06-16 16:35:03

Please allow offline use. We really need it ASAP.

Original issue reported on code.google.com by csdeepu on 2011-06-28 12:58:04

Yes, yes please.  I have been working on a page the contains a number of charts and
dashboards and from a performance pov sometimes its just too slow.  Also if our internet
connection goes down, the office folk should still be able to use the charts/dashboards.

I need this as well...this just became a no go with this api due to this problem

Original issue reported on code.google.com by davidj2k on 2012-04-20 18:19:34

take this offline, we are ready to pay ! 

My organization doesn't like that that data is being sent to you guys , you know goverment
senstive stuff.

Original issue reported on code.google.com by hus.mhd on 2012-11-14 08:11:43

for a professional development this is a must. I'm using another lib (against my will
because I LOVE the API) but, for several reasons (intranet restrictions, speed, data
confidenciality, reliability) I cannot work with an online solution.

I don't see the point of not release from times to times an offline version.

This would have really helped me today faced with loads of "NetworkError: 502 Bad Gateway

Original issue reported on code.google.com by artfulrobot on 2013-10-01 16:25:51

Would have used it, but requiring an internet connection to https://www.google.com/
is an absolute no-go for almost every commercial software development. Sadly looking
for an alternative!

has anyone found a suitable graphing/charting alternative to google-visualization that
can be used offline (without an internet connection /  connection to www.google.com)?

What is the status of this ?

@albertolobrano As far as I know, this is a Terms of Service issue more than a technical one. Google has requested that we download the library from their servers for use. I follow some of the other support channels for this API and I haven't seen any indication that this is likely to change, though I don't work for Google so I wouldn't have inside knowledge.

I am building an application with polymer and firebase which they support offline mode and i was hoping the charts could do the same. Let's see if someone from google will notice this thread and come back with more information.

+1 offline use is a must.

I am in favor of offline use of this API

Please google.
The request of offline is very important for us

Detracts from the user experience in apps hosted in local networks that demand authentication for internet access.

I Download bellow links:

and use them in google charts:

<script type="text/javascript" src="jsapi"></script>
<script src="corechart" type="text/javascript"></script>
<link href="uien.css" type="text/css" rel="stylesheet">
<script src="format.js" type="text/javascript"></script>
<link type="text/css" rel="stylesheet" href="tooltip.css">

Please up the priority for this, Google Charts is brilliant but this is a major showstopper.

https://developers.google.com/chart/interactive/faq unfortunately states:

Can I use charts offline?
Your users' computers must have access to https://www.google.com/jsapi in order to use the interactive features of Google Charts. This is because the visualization libraries that your page requires are loaded dynamically before you use them. The code for loading the appropriate library is part of the included jsapi script, and is called when you invoke the google.load() method. Our terms of service do not allow you to download the google.load or google.visualization code to use offline.

I have been using Google Charts to provide visualisations for a household electrical control system. This restriction means that the users won't be able to see their system if the internet connection goes down. At the least it would be good if it was OK to maintain a long-lived cache that could be preemptively updated so that (for example) one or two accesses per month were sufficient.

Please at least tell us if there is a possibility for offline use in the future.
Based on this we can make an informed decision about using this library or not.

Later edit: Just in case anybody might be interested, I found that D3 charts libray suited my needs better and allows offline use. It also has a GWT wrapper (which was one of my requirements).

@mihajul This issue has actually never received a reply from a Google staffer, which probably says a lot. I've seen comments in the mailing list that they would like to provide this, but under the current Terms of Service, it is prohibited. So, if you need to make a decision, assume the status quo will continue.

Further evidence is that the team continues to put effort into the loader mechanism, rather than providing a static versioned endpoint, which would be preferable for offline use.

The dynamic loading is also a problem for use in Chrome / Firefox / Safari extensions. It's not that you can't access the dynamically loaded code, it's that reviewers are rejecting extensions that load and execute code from an external source. I just had my extension pulled from the Mozilla site because of this (and also the use of eval in Google's code).
