[FlowmapBlue](https://flowmap.blue) 
 is a free tool for representing aggregated numbers of movements between geographic
  locations as flow maps. It is used to visualize urban mobility, commuting behavior, 
  bus, subway and air travels, bicycle sharing, human and bird migration, refugee flows, 
  marine traffic, freight transportation, trade, supply chains, scientific collaborations,
   epidemiological and historical data and data on many other topics.



The project [won bronze](https://twitter.com/kachkaev/status/1197262339935997952) 
at the [Information is Beautiful Awards](https://www.informationisbeautifulawards.com/showcase/3815-flowmap-blue) 
in 2019. 

  
Until recently making flow maps has involved manual drawing, knowledge of programming or 
specialised software. 
 I had learned from my experience developing
 [flow](https://github.com/ilyabo/jflowmap)
 [mapping](https://github.com/ilyabo/jflowmap.js)
 [libraries](https://github.com/teralytics/flowmap.gl)
 that there was a need for an *easy-to-use* tool with which people without special 
knowledge could make flow maps. 
This is why I decided to develop flowmap.blue. 
The tool makes it possible to publish interactive flow maps from data uploaded to Google Sheets.
 It's free, it requires no installation and allows anyone to create a flow map in no time.

An interactive map showing incidents that have resulted in potential civilian impact or harm since Russia began its invasion of Ukraine in 2022. The incidents have been collected by [Bellingcat researchers](https://ukraine.bellingcat.com/). Included in the map are instances where civilian areas and infrastructure have been damaged or destroyed, where the presence of civilian injuries are visible and/or there is the presence of immobile civilian bodies.

Testimonial from <a href="https://resourcematters.org">Resource Matters</a>:
<blockquote><i>
We collaborated with Ilya on the development of a platform visualizing transactions along supply chains of several cobalt-containing products. We were very satisfied with the results. After a quick introductory call, Ilya presented a mockup that ended up being pretty much the final version, at the same time that he solved a big issue we had with our data at the beginning. Further work then consisted in increasing our initial ambitions of data to display. The back and forth was always speedy. By asking the right questions, Ilya understood (and made us understand, which is more complicated as we are not visualizations experts) easily what we wanted to communicate and how to make it more clear and user-friendly. The final product achieves a balance between being light, beautiful, and self-explanatory, in a much better way than we could ever imagine. We plan to continue working with Ilya for future iterations of this platform and also future projects, and would very much recommend other companies to hire his services.

Testimonial from <a href="https://www.linkedin.com/in/frederic-muench-md-72b56042/">Frederic Muench, MD,

<blockquote><i>
We collaborated with Ilya in a COVID-19 intensive care unit project at the university hospital Charité Berlin and were thrilled by his work. Within a week after kick-off we had a working and stable online tool which incorporated more functionalities than expected and its usability and design (which was crucial to the project) was just great! Ilya had additionally optimised our initial idea which in the end resulted in a much more broadly usable tool. He also agreed to modify the tool for a follow-up study. The results of the projects are currently in review and will be published for the medical community soon. This would not have been possible without Ilya's commitment and effectiveness. We definitely endorse Ilya and his work, and really hope to further collaborate!

Here you can see that there is a very high correlation between the turnout (the percentage of people who voted) and the vote for Putin. This correlation is most probably due to the fact that in the polling stations where the turnout was reported as unlikely high votes for Putin were injected.
Anoter anomaly is “the grid pattern”, that is, the higher concentration of reported turnout and vote for Putin around 75, 80, 85, 90, 95%. This is a clear evidence of fraud.

## Estimating the amount of fraud

This simple visualization allows to estimate the amount of fraud by eliminating one of the suspicious anomalies of the vote distribution, namely, the correlation between turnout and vote for Putin. Click for the interactive version:

In this research study we analyzed ﬁndings made by the participants with ﬂow maps using animation and small-multiples as two alternative ways of representing temporal
changes. 

![](interaction-timeline.png)

The goal was to ﬁnd out whether there are qualitative differences between the types of ﬁndings users make with these two representations. 
This required a deep analysis of the collected ﬁndings and the interaction logs. To enable this analysis
I developed web based tools for collaborative  classification of the findings, resolving disagreements in the classification and a visualization of the interaction logs.

User study on visualizing temporal changes in flow maps

Flow map user study


Flowstrates extend the idea of a [flow map](http://en.wikipedia.org/wiki/Flow_map) (which are used for representing entities flowing between geographic locations) to the temporal dimension and allow to analyze the changes of the flow magnitudes over time. In Flowstrates the origins and the destinations of the flows are displayed in two separate maps, and the temporal changes of the flow magnitudes are displayed between the two maps in a heatmap in which the columns represent time periods.

As in most flow maps which focus on representing the flow magnitudes, the exact routes of the flows are not accurately represented in Flowstrates. Instead, the flow lines are rerouted so that they connect the flow origins and destinations with the corresponding rows of the heatmap, as if the flows were going through it. The flow lines help to see in the geographic maps the origins and the destinations corresponding to each of the flows shown in the heatmap.

Flowstrates are meant for interactive exploration. Unlike OD-matrices which represent exactly one flow in each matrix cell, in Flowstrates every flow occupies one whole row of the heatmap for showing how the flow changed over time. Hence, much more screen real estate is used to represent the same number of flows, and for many datasets it is impossible to display all the flows simultaneously on the screen without filtering or aggregating them. Therefore, to allow the users to explore the whole data in every bit of detail Flowstrates provide interactive support for performing spatial visual queries, focusing on different regions of interest for the origins and destinations, zooming and panning, sorting and aggregating the heatmap rows.

You can also read our [paper on Flowstrates](/assets/flowstrates-eurovis11-fin.pdf) published in Computer Graphics Forum.

Flowstrates is a part of JFlowMap, an open-source tool for the analysis of spatial interactions.

Edge bundling


A visualization tool in which we experiment with various visualization techniques for spatial interactions, i.e. interactions between pairs of geographic locations. These can be migrations, movement of goods and people, network traffic, or any kind of entities "flowing" between locations. Spatial interactions are often represented as origin-destination data, meaning that only the origins, the destinations and the magnitudes of the flows are known, but not the exact flow routes.

JFlowMap can be downloaded from [here](https://code.google.com/p/jflowmap/downloads/list).

[BirdEye](http://code.google.com/p/birdeye/) is a Flex visualization library which follows the approach to building visualizations described by Leeland Wilkinson in his book "[Grammar of Graphics](http://www.amazon.com/Grammar-Graphics-Statistics-Computing/dp/0387245448)". BirdEye can be seen as a language for creating visualization which not only provides a set of predefined visualization types, but also allows the users to create new kinds of visualizations easily.

My contribution to BirdEye so far has been to make the animated graph layouts from the previous library version work within the new framework based on the Grammar of Graphics.
