Ok, before saying that this question is too "opinion based" and voting it down, hear me out. I have a geo visualization project in which I'm trying to plot air crash locations on a world map with a hover/mouse over function. I have a map ready. In fact I have two maps ready, a globe one and a flat one. I also have a CSV file with 5000 observations. They do not have longitudes and latitudes. How would I go about plotting the locations in the CSV onto the map?
I'm not looking for code, I'm asking the community for tutorials and ideas. If you can guide me to someone's blog or description or videos on how to do this, that will be awesome. Again, before down voting as "too broad" or "too opinion based" or as some other thing, please read the question again. If you still think the question isn't properly asked, throw in a comment and I'll edit it. Globe Map and Flat map with hover function
Here is a way to geocode your place names to latitudes and longitudes.
More importantly, do you really need D3.js for this? Is this just for practicing? If yes, then these video tutorials are a great place to start.
If not, and if you care about displaying information on hover, why not use a simple solution like CartoDB? It will serve your purpose pretty well. You can customize the colors, basemaps, tooltips, fonts and most other things you'd care about in a map.

I want to create a Google my map from a KMZ formatted google sheet and have the two linked. I have both points and polygons I want shown on the map. I want the map to update when I change the information on the google sheet. I am a field man for a large hay and straw co-op. I would like to use this map not only for directions but also as a harvest tracker. I am going to put check boxes in column c-f to track different activities and put a unique pin based on what box is checked. for example if a the check box is marked saying the field has been baled I want a particular pin to appear over the field to show that on the map. I can figure out how to script in my check box goal once I have the main script figured out.
I need help figuring out how to write the main script in notepad. I have very little experience with script or API's so I'm a little lost. Any help would be greatly appreciated. I can figure out how to start a project in google console and how to generate an API once I enable javascript API. IM pretty much stuck at this point though.
I have made a project in google console. i enabled maps javascript and google sheets. I generated an API for the project. I have a KMZ file for my points and polygons.

I want to plot a graph (diagram) on html pages, and the graph could consist of multiple nodes (sub-graph). When a user clicks a node, I need to display some textual message somewhere on the page. Is this can be done by some JavaScript plot library? A google search found:
Google Charts
ChartJS
DS.js
and more. Clearly, it can draw the photo for me, but my question is whether it can respond to user's action, i.e. a mouse click to display information for the graph. I have never used this and please share your knowledge.
you can try with d3.js. It is a good library to draw graphs.User interactions like mouse click also possible using d3.js
If you're a beginner, I'll advise you to use Chart.js or Chartist.js, the other ones being quite more complex to handle with (especially D3.js).
Your question is really really wide. If you want to be able to interact with user actions that happen within the graph, you should look at the events parts of their documentation and/or possible callbacks. A good example is in Chart.js when a user is over an element :
onHover Called when any of the events fire. Called in the context of the chart and passed an array of active elements (bars, points, etc)
You'll find many examples in their documentation and with a quick research through your favorite search engine.

I was looking at some leaflet maps and they are sooo cool and impressive! The only downside is that it appears that a lot of buildings are missing from the map. Are their third party plugins to overcome that or maybe a way that I can contribute to help fill in those buildings? Thanks for any suggestions in advance!
The buildings are part of the tile layers displayed using Leaflet, and not of Leaflet itself. Most of the time, Leaflet maps are using OpenStreetMap tiles, to which you can contribute too.

Also, you can have a look at the multiple tile layers available, maybe you'll find something that suits your needs:

I need to display a map of multi-level building on a website. This website will only be displayed on a PC in the foyer of this building.
I need to allow people to do a room search and then draw directions to the room on the map. I also need people to zoom and drag the map too.
I have watched the Google "Map your business, inside and out" video and can see a lot of that could be useful, but there is nothing there to be able to show directions from one room to another.
So before I spend a lot of time writing my own code using jQuery, I was wondering if anyone else has done something similar, or if anyone can suggest some good starting points?
I found really nice plugin that meets my requirements.

I am trying to make custom Google maps. The idea is to make a map with 3 different markers for example: forest, river, lake.
I know how to add these custom markers. I do this with this tutorial, but I need to sort markers. For example when I press link "forest" in map will show only "forest" markers. Please help with this question, I try search in Google example, but found nothing that I need.
I simply keep a list / array of all markers for a similar scenario. Actually I have written a Javascript meta object for this purpose, so I can search for all markers of a particular type etc.
A very simple solution is to keep three lists, one for each type. So you can iterate over all lists and hide/display the markers as appropriate.
Edit 1:
See https://stackoverflow.com/a/6662514/356726 to get a first impression.
Here a tutorial using the concept in combination with jQuery.
