i am using Google Fusion Tables and Google Maps to display geographical data (e.g. markers). My map needs to have a legend, for example by inserting a div on top of the map and the layer. As i am not used to work with API of any kind, i got stuck with this legend problem.
I tried several example codes (most of them provided by google), but none worked for me. I guess that the problem of displaying divs on a map has got something to do with either the styling of the map canvas, the div implementation within the body of the html document or with the framework used (google appengine). But this is just guessing. As i am not a professional with coding, i maybe missed a important point. Maybe the folks here can help me out?
Every hint is appreciated. Thanks.
You can have a look at the code and my example [here (deleted)]. There example includes a code which should display a div, but it doesn't. I've taken it from here (Stackoverflow).
The code you're using is v2 of the Maps API. You'll want to use code that works with v3 of the Maps API, since that is the version you're using on your site.
Have you tried the sample code here?
https://developers.google.com/fusiontables/docs/samples/legend
Copy and paste the legend code from this example into your initialize method, remove the old legend code. If this doesn't work, let me know.

I'm working on a React Native app, and I'd like to create a function for sharing contents in Instagram stories, like the tweet below.
How can I generate a custom template, like Twitter does, using Python? Because my backend is written in Django.
=== UPDATE ===
I have done some research and found out that you can use various languages, such as FabricJs or PIL in Python, to draw an image. However, these can be a nightmare for high-complexity stickers. Therefore, my solution is to simply take a screenshot in the app using react-native-view-shot.
If someone has any better solutions, they would be greatly appreciated.
Thank you.
Websites previews based on website meta tags like open graph
You can use this library to generate it https://github.com/tjcages/expo-link-preview.
However, it maybe a better solution is to build these previous on the backend like here https://github.blog/2021-06-22-framework-building-open-graph-images/
And then share image with https://github.com/react-native-share/react-native-share
Creating Modified Blog Entries
I am new to React, and very much to Docusaurus, however, I've managed to get a decent looking DS site going. I am trying to capture some simple snippets to as "blog entries", just small factual snippets, etc. simple project summaries. I’ve hit the limit of the Docusaurus.config options and not sure how to expand the out of box components.
How do I begin to alter and edit Docusaurus to change the Blog page to be like "Cards" in component-speak? Ive seen some example in Infima, but not sure how to bridge that gap?
How can I easily replicate the Announcement Bar to also be at the bottom, like a Banner?
Thank You!
One possible arena for you to use is Bootstrap — specifically React-Bootstrap. They have a card component you could use where you link individual blog entries to that card. If you're comfortable with JavaScript, there's probably an automation you can build there, but hand-coded text is somewhat part and parcel with static-site generators.
If you want a different solution with the CSS code in your src file outright, CSSCodeLab has a React Card layout entry with an attached source code file. Some hand-coded text required, and not automatically integrated with a separate blog setup, but YMMV.
Otherwise Docusaurus' Showcase page does provide the card formatting. The source code for the page (coded at index.tsx) as well as the components are available.
I want to implement a map like this:-
in which vector layers of countries are highlighted according to some metric value. I tried to search for some package but found JQuery based JQVMaps and jvectormap, which I want to avoid to use since my framework is VueJS.
Can someone suggest some package for this? Or should I go for integrating these Jquery based packages itself?
Leaflet is great and simple to learn library to work with maps. Fortunately there is a wrapper called vue2-leaflet that make it work with Vue. Regarding your Image this part of docs may useful for you.
There are several examples in the API, but for some reason, what I think the biggest feature is eluding me for some reason. I have a list of points and each point needs to be represented by a different icon. I also may have layers that use the same icon which I can find, just not the option for different icons/markers. An example of this would be greatly appreciated!!
I found out how to use the Graphic option to add an array of points that have a different url for their markers (symbols). This used the Picture Marker type. The beauty of JSON!!
Cheers,
for about a year now Google allows you to adjust the styling of their maps according to your needs. They offer a tool which allows for the easy creation of styles too:
Google Maps API Styled Maps Wizard
What I'd like to know is: can this feature of their API be used with MKMapView as provided in the Map Kit Framework? If so, how and at which point would I feed the JSON code which the wizard produces to the API?
If this doesn't work with MKMapView: What's the next best way to include Googles Styled Maps in an app?
Thanks alot!
As far as I'm aware, MKMapView doesn't provide this functionality "out of the box" as the Google Maps API does; the class reference, seems to support this hypothesis. You could re-implement some of the styles using annotations and overlays (see the class reference), but that assumes you have access to the point of interest data. Your success will likely depend on what styles you want to use.
As for the next best way, I opened your link, the styled maps wizard, on my iPad and it seems to work flawlessly. Perhaps you could host a pre-styled map somewhere online and simply show it in your app using a UIWebView? That would obviously limit you in some ways, but at least it would be styled!
