topojson.feature with topojson v2 - node.js

I've been following the "let's make a map" tutorial https://bost.ocks.org/mike/map/, however in the middle of the tutorial, drawing the paths failed with errors about topojson.feature() is not a function.
script.js:14 Uncaught TypeError: topojson.feature is not a function(…)
(anonymous function) # script.js:14
(anonymous function) # d3.min.js:6
call # d3.min.js:6
e # d3.min.js:6
script.js:
var width = 960,
height = 1160;
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height);
d3.json("js/uk.json", function(error, uk) {
if (error) return console.error(error);
console.log(uk);
svg.append("path")
.datum(topojson.feature(uk, uk.objects.subunits))
.attr("d", d3.geo.path().projection(d3.geo.mercator()));
});

Originally I've suspected the issue to be with the topojson file I've converted Pathfile-GeoJSON-TopoJSON, I've names it uk.js for testing purposes while following the tutorial.
Another hint as mentioned in the reply here:
https://github.com/topojson/topojson/issues/236
However after changing the issue remained the same, and confirmed after substituting uk.json I've creted myself with:
https://bost.ocks.org/mike/map/uk.json

You are missing the topojson client files, which have been split off from the base topojson code in v2. If you include the following script in your code, it should work:
<script src="https://unpkg.com/topojson-client#2"></script>

Simple SVG project cause error on Internet Explorer 11

I am learning svg and would like to compare displaying svg items on different browsers. My code works fine on firefox, chrome, edge, safari etc, but cannot work on ie11. Unfortunately application I develop needs to support ie11 so I need to force my code to work correctly.
Here is fiddle: https://jsbin.com/hemawaboqa/1/edit?html,js,output
HTML
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/#svgdotjs/svg.js"></script>
</head>
<body>
<div style="position:absolute;left:0px;top:0px;right:0px;bottom:0px;overflow:hidden;" id="svg-main-container">
<div style="position:absolute;left:0px;top:0px;bottom:0px;right:300px;border:1px solid #dadada;overflow:auto;" id="svg-canvas"></div>
</div>
</body>
</html>
JS
var draw = SVG().addTo('#svg-canvas').size(400, 400)
var rect = draw.rect(100, 100)
Why that code is not working on ie11?
I have created a sample using the SVG.js 3.0 version with your code, it will show the "Object doesn't support property or method 'from'" in IE11 browser, perhaps the issue is related to the svg.js version, and it is a plugin issue, you could feedback this issue to SVG.js forum.
Besides, I suggest you could refer to the following code, to use the old version of SVG.js:
<!DOCTYPE html>
<html lang=en-us>
<head>
<meta charset=utf-8>
<title>TEST</title>
</head>
<body>
<div style="position:absolute;left:0px;top:0px;right:0px;bottom:0px;overflow:hidden;" id="svg-main-container">
<div style="position:absolute;left:0px;top:0px;bottom:0px;right:300px;border:1px solid #dadada;overflow:auto;" id="drawing">
</div>
</div>
<script src=https://cdnjs.cloudflare.com/ajax/libs/svg.js/2.6.6/svg.min.js></script>
<script>
(function () {
'use strict';
// Add title as first child of SVG element:
var createTitle = function (svgObject, text) {
var fragment = document.createDocumentFragment();
var titleElement = document.createElement('TITLE');
fragment.appendChild(titleElement);
titleElement.innerHTML = text;
svgObject.node.insertAdjacentElement('afterbegin', titleElement);
};
SVG.extend(SVG.Doc, {
namespace: function () {
return this
.attr({xmlns: 'http://www.w3.org/2000/svg', version: '1.1'})
.attr('xmlns:xlink', SVG.xlink, SVG.xmlns);
}
});
var draw = new SVG('drawing').size(300, 300);
var rect = draw.rect(100, 100).attr({fill: '#f06'});
// Add title to SVG element
createTitle(draw, 'Rectangle');
}());
</script>
</body>
</html>
The result as below:
The library you are using has ECMA 6 elements that are not understood in IE.
If you need your project to work in IE, you will have to use another library or find out how to change it so it allows for older browsers (as suggested here: https://svgjs.dev/docs/3.0/compatibility/)

gmplot Google Maps html output not showing markers/heatmap

I am running gmplot in Pycharm (2018.1 Community) with Python Interpreter 3.5.4 (via Anaconda 1.5).
gmplot definitely creates the map.html, and the lat/longs are listed in the html.
However it does not appear to be plotting the lat/long on the image.
What am I missing?
Python Code:
gmap = gmplot.GoogleMapPlotter(lats[0],longs[0],15) #working
gmap.heatmap(lats, longs) #not working
gmap.draw('map.html')
HTML Output:

And when I try to open the html file direct from PyCharm, I get Javascript errors that look like this:

This happens regardless of whether I use gmplot.scatter or gmplot.heatmap.
Do I need to put an API key somewhere?
Any ideas?

how the inherit happened in phaser

I just use Phaser and saw some example code like below. In the Rox.Boot.prototype function, the .load, .physics, etc, are all in game(Phaser.Game). How does this inheritance happen?
Rox = {
score: 0,
music: null,
orientated: false
};
Rox.Boot = function (game) {
};
Rox.Boot.prototype = {
preload: function () {
this.load.image('preloaderBar', 'images/preload.png');
},
create: function () {
this.physics.startSystem(Phaser.Physics.ARCADE);
this.input.maxPointers = 1;
this.state.start('Preloader');
},
};
To use Phaser, you have to have a phaser.min.js or phaser.js file which you can get here. I use the phaser.min.js file instead of the phaser.js file because I don't need the extra features that the phaser.js file has (debugging); phaser.min.js will have all the same methods, classes, properties, etc as phaser.js.
They tell you to download the whole GitHub repo, but really you just need the Phaser JS file.
After you add the phaser.min.js file to your project, make sure it's the first script you call in the head of your HTML file; you should be able to use Phaser in the following JS files after that.
Here is what my index.html looks like:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>FILL_IN_GAME_NAME_HERE</title>
<script src="phaser.min.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="Main.css">
<script src="Boot.js" type="text/javascript"></script>
<script src="Preloader.js" type="text/javascript"></script>
<script src="Menu.js" type="text/javascript"></script>
<script src="Game.js" type="text/javascript"></script>
<script src="GameOver.js" type="text/javascript"></script>
<script src="HighScores.js" type="text/javascript"></script>
</head>
<body>
<script type="text/javascript">
var game = new Phaser.Game(500, 500, Phaser.AUTO, 'game', false, false);
game.state.add('Boot', Game.Boot);
game.state.add('Preloader', Game.Preloader);
game.state.add('Menu', Game.Menu);
game.state.add('Game', Game.Game);

Node.js and swig template engine - including template inside template

I trying to create main page (part of node.js and mongoDB application) that includes login form.
To add view part I included js files with function that returns HTML, but as I can see much better is using template engine.
Everything is OK until I including one compiled swig part inside another one.
The output of main page is OK, but login part outputs like text on the page.
How is possible to output the login HTML as HTML instead of plain text?
Does more information needed to understand the issue?
Thank you in advance.
var swig = require('swig');
var mainPage_tpl = swig.compileFile(__dirname+'/../views/mainpage_tpl.html');
var formLogin_tpl = swig.compileFile(__dirname+'/../views/login_tpl.html');
var loginOutput = formLogin_tpl();
var mainPageOutput = mainPage_tpl({
title: 'Sometitle',
pagetitle: 'Somepagetitle',
content: loginOutput
});
exports.get = function(req, res){
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(mainPageOutput);
res.end();
}
mainpage_tpl.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>{{title}}</title>
<link rel="stylesheet" href="/assets/reset.css" />
<link rel="stylesheet" href="/assets/style.css" />
<script type="text/javascript" src="/assets/jquery-2.0.0.js"></script>
<script type="text/javascript" src="/assets/script.js"></script>
</head>
<body id="login_page">
<h1>{{pagetitle}}</h1>
<div id="content">{{content}}</div>
</body>
</html>
If you want to include literal HTML, you need to tell Swig to not escape it using the safe filter:
...
<div id="content">{{ content|safe }}</div>
...

Script stops at YAHOO.util.Event.addListener

I am new to YUI. Just trying to get a most basic functioning example working on my site.
Here is the code:
<button id="mytest">test</button>
<script type="text/javascript">
var helloWorld = function(e) {
alert("Hello World!");
}
</script>
<script type="text/javascript">
alert('xx');
YAHOO.util.Event.addListener("mytest", "click", helloWorld);
alert('x2');
</script>
The xx alert shows, but the x2 alert never does. And, clicking on the button does not fire the HelloWorld function.
I have the necessary include files:
<!-- Required CSS -->
<link type="text/css" rel="stylesheet" href="http://yui.yahooapis.com/2.8.1/build/progressbar/assets/skins/sam/progressbar.css">
<!-- Dependency source file -->
<script src = "http://yui.yahooapis.com/2.8.1/build/yahoo-dom-event/yahoo-dom.event.js" ></script>
<script src = "http://yui.yahooapis.com/2.8.1/build/element/element-min.js" ></script>
<!-- Optional dependency source file -->
<script src="http://yui.yahooapis.com/2.8.1/build/animation/animation-min.js" type="text/javascript"></script>
<!-- ProgressBar source file -->
<script src = "http://yui.yahooapis.com/2.8.1/build/progressbar/progressbar-min.js" ></script>
you should be sure the js files are included on you html files,the code your write is write!
Believe I found it. Or at least I was able to find other examples which worked. But in my case I believe the problem is the js files I was referencing in fact did not exist. Namely this file:
http://yui.yahooapis.com/2.8.1/build/yahoo-dom-event/yahoo-dom.event.js
sure, it is yahoo dash dom DASH event, not yahoo dash dom DOT event
