Use of the original data visualization design studies and the separate steps needed to agree an actual project with Marius Jasevicius.
1. Operator and use of the portfolio
The website is presented by MARIUS JASEVICIUS, an independent professional using the public name Marius Jasevicius. The identification address is 3700 McKinney Ave, Apt 2107, Dallas, TX 75204-1687, United States, and the contact route is an email draft to [email protected]. These terms cover access to the portfolio, its concept studies, service descriptions and enquiry tools. They do not by themselves create a design commission, partnership, employment relationship or agency appointment. Reading a page or preparing a message does not indicate that a project has been accepted.
2. Permitted browsing and fair use
You may browse the pages, follow their navigation and refer to the work when discussing a potential design project. Use the site in a way that respects other people's rights and the availability of the service. Do not impersonate another person, submit misleading identity information, interfere with the site's operation or attempt to gain access to systems that are not publicly offered. A public portfolio is an invitation to view the material; it is not a general license to republish the artwork or sell it as your own.
3. Meaning of the concept studies
Balance / a visible comparison and Daylight / patterns across a day are independent original studies for fictional briefs. The accompanying notes explain visible choices in data visualization design, including the question behind each composition and the material included. These studies are not commissioned client work, published case results or testimonials. A chart is a representation of supplied information. It does not independently validate the dataset, establish causation or replace financial, scientific or other specialist analysis. Fictional sample values must not be quoted as real findings. The concept description belongs with the image; removing it could create an inaccurate impression of the work. A real engagement starts from the actual source content and its permissions, rather than treating the portfolio’s invented scenario as an operational brief.
4. Service descriptions and project fit
A request can begin a discussion about data visualization design, but no project is accepted by viewing a page or preparing an email. A proposal needs to establish the intended audience, the available source material and the specific work to be delivered. Source formats, chart types, annotation requirements, accessibility needs and static or interactive output are matters for the actual scope. Timing, fees, revisions and usage rights require agreement before relying on a production commitment. No portfolio label or concept title is a current quotation. An email draft remains under your control until you decide to send it through your own service.
5. Enquiries and email drafts
The form prepares a message for review and offers a mailto link to your email application. It does not send the message from a website server, take payment or reserve time. You decide whether to send the draft through your own email service, and can edit it beforehand. A generated draft is not an acknowledgement of receipt. Email services may reject, delay or fail to deliver messages. Any confirmation of scope, receipt or acceptance must come from the actual conversation, not from the website's draft preview.
6. Proposals and agreement
A visualization engagement needs an agreed question, source definitions and output specification. State whether the deliverable is a report graphic, a diagram, a dashboard concept or a working interactive implementation. Balance and Daylight demonstrate static visual decisions on fictional inputs; viewing them does not purchase a live analytics service. Data cleaning, connections, refresh scheduling, testing and specialist interpretation require explicit scope when needed. Agree who validates the inputs and approves the labels before relying on a chart in an actual publication or decision.
7. Fees, payments and availability
The portfolio has no checkout and does not publish a standard price list. No payment is collected through its enquiry form. A proposed fee, deposit, invoice method or cancellation arrangement must be established in the actual project discussion, together with any applicable currency and relevant charges. Similarly, a preferred deadline entered in the form is a request rather than a confirmed delivery commitment. Do not send card numbers or banking credentials in the message. Verify payment instructions in the agreed communication before making any separate project payment.
8. Materials supplied for a project
Describe the source, definitions and permitted use of any data proposed for a visualization. A table’s availability does not automatically permit its republication or use in a different setting. Personal information, confidential measures and third-party marks require appropriate authority. The person supplying the material should identify restrictions and responsibility for checking accuracy. Clarify whether the design uses sample, historical or current observations. A visual treatment can make those inputs readable, but it cannot create missing permission or independently establish that they are reliable.
9. Intellectual property and files
Supplied data, report copy and third-party marks need appropriate permissions for the intended output. A public dataset may carry attribution or redistribution conditions, while a confidential table may have access restrictions. The visual design and the underlying information can have different rights holders. File handover does not automatically remove those restrictions or grant access to an external system. Establish source attribution, editing permissions, required file formats and any reuse licence within the engagement instead of assuming that a portfolio example defines them.
10. Third-party services and production
Your email application, network access and any separately chosen publishing, software or hosting provider have their own terms and technical behaviour. A portfolio example cannot certify compatibility with every browser, document format, device or data source. A commissioned project needs agreed target environments, input formats, file handover, licences and acceptance criteria. Third-party subscriptions, live hosting, operational monitoring and external data access are not automatically included. Responsibility for factual checking, publication approval and any specialist review should be assigned before relying on a deliverable in a real service or decision.
11. Accuracy, access and responsibility
A polished graphic cannot guarantee that an input is complete, that two variables are causally related or that a business decision will succeed. Illustrative values in these studies must not be used as actual research findings. In a commissioned report, the parties should identify the responsible factual reviewer and the target audience. Website access and email delivery also depend on independent technical services. These conditions preserve mandatory rights and do not replace any specific responsibility accepted for an actual visualization task.
12. Changes, questions and related notices
The displayed revision date identifies this version. Later updates apply to the website as published; they do not silently amend a separately agreed commission. Consult the Privacy policy for the form and data workflow, the Cancellation and refund policy for the distinction between an enquiry and a paid project, and the Portfolio disclaimer for the status of examples. If you need to clarify use of the portfolio or a proposed engagement, prepare an email to [email protected]. Include the relevant page or agreement so the question can be understood in context.
