kandi X-RAY | Mediaviz Summary
Mediaviz is a network visualization library created for my project Automating Force Based Layout Scaling And Network Visualization For Media Source Networks From MediaCloud Topic Graphs done with Berkman Klein Center of Internet And Society at Harvard University while participating at Google Summer Of Code 2018 under the guidance of mentor Hal Roberts. Mediacloud is an open source, open data platform for researchers that provides data and statistics for quantitative analysis. Mediaviz has been originally developed to automate the network visualization of the media source networks for different topics such as network neutrality, ebola and more. However, beyond the mediacloud usage, Mediaviz is also a general purpose network visualization library. It provides functionalities for force based layout such as force atlas 2, automatic scaling to prevent node overlap, Gephi like features for network filtering, coloring, node resizing, prevention of label overlap and community visualization. Mediaviz uses force atlas 2 layout as default and scales the layout automatically for graphs with 100-1000 nodes that has a power law linking structure. Having sensible defaults, Mediaviz can be used for general graph visualization as well as publishable graphs with many customization parameters including using the drawing function with any other network layout function in networkx or beyond. Examples and demo visualizations are provided in the usage section.

QUESTION
I made the following 25 network graphs (all of these graphs are copies for simplicity - in reality, they will all be different):
...ANSWER
Answered 2022-Mar-03 at 21:12While my solution isn't exactly what you describe under Option 2
, it is close. We use combineWidgets()
to create a grid with a single column and a row height where one graph covers most of the screen height. We squeeze in a link between each widget instance that scrolls the browser window down to show the following graph when clicked.
Let me know if this is working for you. It should be possible to automatically adjust the row size according to the browser window size. Currently, this depends on the browser window height being around 1000px.
I modified your code for the graph creation slightly and wrapped it in a function. This allows us to create 25 different-looking graphs easily. This way testing the resulting HTML file is more fun! What follows the function definition is the code to create a list
of HTML objects that we then feed into combineWidgets()
.

QUESTION
I'm trying to build a doughnut chart with rounded edges only on one side. My problem is that I have both sided rounded and not just on the one side. Also can't figure out how to do more foreground arcs not just one.
...ANSWER
Answered 2022-Feb-28 at 08:52The documentation states, that the corner radius is applied to both ends of the arc. Additionally, you want the arcs to overlap, which is also not the case.
You can add the one-sided rounded corners the following way:
- Use arcs
arc
with no corner radius for the data. - Add additional
path
objectscorner
just for the rounded corner. These need to be shifted to the end of eacharc
. - Since
corner
has rounded corners on both sides, add aclipPath
that clips half of this arc. TheclipPath
contains apath
for everycorner
. This is essential for arcs smaller than two times the length of the rounded corners. raise
all elements ofcorner
to the front and thensort
them descending by index, so that they overlap the right way.

- Your data
QUESTION
In d3
, we may change the order of elements in a selection, for example by using raise
.
Yet, when we rebind the data and use join
, this order is discarded.
This does not happen when we use "the old way" of binding data, using enter
and merge
.
See following fiddle where you can click a circle (for example the blue one) to bring it to front. When you click "redraw", the circles go back to their original z-ordering when using join
, but not when using enter
and merge
.
Can I achive that the circles keep their z-ordering and still use join
?
ANSWER
Answered 2022-Feb-18 at 23:13join
does an implicit order
after merging the enter- and update-selection, see https://github.com/d3/d3-selection/blob/91245ee124ec4dd491e498ecbdc9679d75332b49/src/selection/join.js#L14.
The selection order after the data binding in your example is still red, blue, green even if the document order is changed. So the circles are reordered to the original order using join
.
You can get around that by changing the data binding reflecting the change in the document order. I did that here, by moving the datum of the clicked circle to the end of the data array.
QUESTION
Is there a way to put text along a density line, or for that matter, any path, in ggplot2? By that, I mean either once as a label, in this style of xkcd: 1835, 1950 (middle panel), 1392, or 2234 (middle panel). Alternatively, is there a way to have the line be repeating text, such as this xkcd #930 ? My apologies for all the xkcd, I'm not sure what these styles are called, and it's the only place I can think of that I've seen this before to differentiate areas in this way.
Note: I'm not talking about the hand-drawn xkcd style, nor putting flat labels at the top
I know I can place a straight/flat piece of text, such as via annotate
or geom_text
, but I'm curious about bending such text so it appears to be along the curve of the data.
I'm also curious if there is a name for this style of text-along-line?
Example ggplot2 graph using annotate(...)

...ANSWER
Answered 2021-Nov-08 at 11:31Great question. I have often thought about this. I don't know of any packages that allow it natively, but it's not terribly difficult to do it yourself, since geom_text
accepts angle
as an aesthetic mapping.
Say we have the following plot:
QUESTION
I do realize this has already been addressed here (e.g., matplotlib loop make subplot for each category, Add a subplot within a figure using a for loop and python/matplotlib). Nevertheless, I hope this question was different.
I have customized plot function pretty-print-confusion-matrix
stackoverflow & github. Which generates below plot
I want to add the above-customized plot in for loop to one single plot as subplots.
...ANSWER
Answered 2022-Jan-04 at 09:09Okay so I went through the library's github repository and the issue is that the figure and axes objects are created internally which means that you can't create multiple plots on the same figure. I created a somewhat hacky solution by forking the library. This is the forked library I created to do what you want. And here is a an example piece of code:

I would like to use a standardized data format which would allow me to quickly construct figures based on standardized datasets containing 25 groups.
For example, a datasheet would look like this:
