I am trying an example provided by networkx here. This example uses a geopandas dataset in a filename cholera_cases.pkdg.
# read in example data from a geopackage file. Geopackages
# are a format for storing geographic data that is backed
# by sqlite. geopandas reads data relying on the fiona package,
# providing a high-level pandas-style interface to geographic data.
cases = geopandas.read_file("cholera_cases.gpkg")
The example, however, does not mention where and how to obtain this dataset. I combed GeoPandas website up and down and am unable to locate this file. I want to view the format of its content and run this example.
If anyone is aware of where to obtain this kind of geopandas file, please advise.
If you go to their GitHub, you can find it in their repo. Here: https://github.com/networkx/networkx/tree/main/examples/geospatial
Might be worth cloning the repo to play with the examples.
As general advice, on webpages for projects like these, I like to always check for links to their GitHub/GitLab/other because you get to see the project behind the scenes, and a local clone can be kept up to date

I have been trying to load some gis data from a postgis database into Cytoscape 3.6. I am trying to get some inDegree and outDegree values I have used the sif file format.
As long as the data is written out in the follow format
source_point\tinteracts with\ttarget_point
Cytoscape is happy to read it.
I am just wondering if there is anyway of including my own metric for the cost of getting between source_point and target_point
Sure! There are several ways to read in text files into Cytoscape -- SIF is just one of them. I would create a file that looks like SIF, but is actually a more complete text file:
Source\tTarget\tScore
source_point\ttarget_point\t1.1
...
And then use the "File->Import Network->File", choose your source and target and leave score as an edge attribute. You can have as many attributes on each line as you want, and can even mix edge attributes, source node attributes, and target node attributes.

I don't know anything about TalenD but have to work,so if anybody can help me out in letting me know how to create mapping and transfer data from suppose a txt file to .xls.
Thanks In advance
You need to find out the format of the txt file.
Then you need to find the appropriate talend input component and read in the data.
You should make clear what your specification of your output format are.
For example if you need conditional formatting or complicated dynamic formulas, you need to find a good Talend output component, for example tFileExcelSheetOutput [1].
Otherwise you could use the standard tFileOutputExcel component.
You would use tMap to map the input to the output and depending on your transformation requirements you might also need additional components.
I would recommend looking at Talend on demand seminars which should be freely available from their website to get yourself familar with Talend Studio. Then you can consult the component reference, which is also integrated into Talend Studio.
If you need further assistance you can describe what you tried and what part exactly doesn't work.

I have created some links between agents (turtles) in NetLogo. This links will change at each time step. My aim is to export this data (i.e., turtles and links b/w them) to graph with vertices (turtles) edges (links), which can be given as input to Gephi. Is it possible to see the changes which occurs in netlogo in the graph when it is linked with Gephi. Can someone help me out. Thanks.
To export your network data in a format usable by Gephi, I would suggest using the nw:save-graphml primitive from NetLogo's NW Extension. This will give produce a file in the GraphML file format, which Gephi can read.
I guess you could re-save your network at each time step and overwrite your file, but I'm not sure if Gephi can display your changes dynamically. And depending on the size of your network, it might be slow.
Are you trying to use Gephi to see how the network changes over time, in a changing network that is generated by NetLogo? That's what #NicolasPayette's answer suggests, so I'll make the same assumption.
Gephi can display "dynamic graphs", i.e. networks that change over time. My understanding is that are two file formats that allow Gephi to import dynamic graphs: GEXF, and a special CSV (comma-separated) format that Gephi calls "Spreadsheet". Nicolas mentioned GraphML, which is a very nice network data format, but it doesn't handle dynamic graphs. And as far as I know, NetLogo doesn't generate GEXF or Gephi's "Spreadsheet" format.
However, the Gephi Spreadsheet format is very simple, and it would not be difficult to write a NetLogo procedure that would write a file in that format. This procedure would write new rows to the "Spreadsheet" CSV file on each NetLogo tick. Then Gephi could read in the file, and you'd be able to move back and forth in time, seeing how the graph changes. (You might need to use a bit of trial and error to figure out how to write Spreadsheet files based on the description on the Gephi site.)
Another option would be to display the evolving graph online using the graphstream protocol. Plugins for NetLogo as well as for gephi provide support for this.
I'm looking for a way to visualize arbitrary information about my repository over time, which might be some version-dependent number, such as:
lines of code
number of lines in a latex document
time between commits
anything that can be output by a script
What is the best way to visualize this information?
More specifically, I'm using mercurial and would ideally like something with a decent interface, with plot resizing/scrolling/etc... Jenkins' plot plugin is decent but not great, but more importantly it's not possible to visualize past data (say, after adding a new metric).
I would suggest to split your task to simplify everything a little bit. It is likely you will need several different tools in order to collect and visualize all required information. Historical view seems to be another big challenge.
Lines of code
There are several plugins available for Jenkins, but almost all are highly specialized. SLOCCount plug-in seems to be most universal, but it does not provide any graphical output.
NSIQ Collector Plugin
SLOCCount plug-in
JavaNCSS Plugin
There might be some other option for your language. For example, CCCC will provide required information for C and C++ code:
Number of lines in a latex document
I see several options to achieve that:
adapt existing solution/plugin
use repository statistics tool (Pepper, for example, can do the trick)
use simple shell script to count lines and report it
Pepper will generate something like the following:
Please check Pepper gallery. There are another tools, for example: hgchart
Time between commits
The simplest solution is to let a commit to trigger some trivial job, so Jenkins will provide all information as part of build history (with a timeline, etc).
Another solution is to use repository statistics tool once again:
Anything that can be output by a script
There are several good plug-ins for that.
Plot plugin can visualize multiple values provided as properties or csv file.
Measurement Plots Plugin scans the output in order to find values to be visualized
Happy continuous integration.
I want to find out files under a given directory which have been updated most. Is there any command which can display this info? Or is there any way to get max version count for a given file, so I can write some script to get this info from all and then sort desc.
Do you mean changed the most number of times, or undergone the most code chrun?
Either way - looking at the report data might be the easiest option for you. Take a look at the following blog post I did explaining how to use Excel for looking at TFS data that uses churn as an example allowing you to drill down into folders and files - but you should be able to get the data that you are looking for.
